Automatic Tuning Based on Transfer Function Estimation
Student: Pablo Tapia Lopez
Advisor: Karl Johan Åström
Date begun: February 1997
Document Number: TFRT-5583
Abstract:
This report describes a method for automatic tuning of PID controllers
in closed loop. A limit cycle is generated through nonlinear feedback
from the process output to the controller reference signal. The
frequency of this oscillation is near the critical frequency of the
loop transfer function. The amplitude and frequency of the oscillation
are estimated as well as process gain in steady state. PID parameters
are calculated adaptively considering factors such as load
disturbances, measurement noise and process dead times. The approach
is compared to methods proposed by Åström and
Hägglund,
Schei, and
Woodyatt and Middleton.

Document Number: TFRT-5581
Abstract:
The paper describes an adaptive local model networks strategy intended
for control of a class of nonlinear, time-varying systems. Some recent
progresses in multiple model identification, local model networks and
switching are combined to a very powerful and flexible strategy. The
method does not need much more computational effort than a
conventional adaptive control scheme. More memory are however needed.
The paper describes all aspects of the method: robust real-time
controller design, robust real-time multiple model identification,
local model networks and switching. A simulation example of the high
performance vehicle speed control is also presented. The work has done
as a part of an ESPRIT III project called Neural Adaptive Control
Technology.

Abstract:
Volvo Excavator AB has problems controlling the number of revolutions

To solve this problem the different processes controlling the
energy-flow in an excavator are mathematically identified. These
models are later put together to enable simulations of a running
excavator on the computer. The different models that needs to be
identified are the diesel engine, the proportional valve and the
hydraulic pumps. When the different models where put together a few
reasons for the earlier problems were discovered. New identifications
are expected on the modified hydraulic pump using this work as a
manual.

A Real Time Control Language for the
Pålsjö Environment
Student: Anders Blomdell
Advisor: Karl Johan Åström
Document Number: TFRT-5578
Abstract:
Traditionally computer based real-time control systems have often been
coded from scratch, involving a substantial effort. Recently the
adoption of domain specific frameworks has made it easier to implement
real-time control systems. Pålsjö is one such
framework
implemented at
the Department of Automatic Control in Lund.
During the construction of the Pålsjö real-time
control
system
framework, it was obvious that ordinary programming languages are not
an optimal choice for the implementation of control algorithms. It was
also apparent that the algorithms got intermixed with framework
specific code. A new language was therefore proposed and implemented.
A properly designed language with data-types and other abstractions
aimed at control engineers simplifies the coding of algorithms. Since
the code executed by the framework is generated by a compiler, the
structures in the framework can be designed for maximum performance
instead of ease of use. The reuse of algorithms in a new or modified
framework is also simplified since only a new back-end for the
compiler is required.
The main focus of the thesis are the syntactic and semantic elements
of the proposed language, but a brief introduction to the compiler
structure is also given as an aid for the implementation of new
back-ends.

Industrial Partner/Sponsor: Kemira Kemi AB
Date begun: September 1996.
Document Number: TFRT-5577
Abstract:
An effort is made to model the steam generation at Kemira Kemi's
sulfuric acid plant in Helsingborg, Sweden. The making of sulfuric acid
starts
with the oxidation of elementary sulfur in an exothermic reaction. The
released energy is used in the waste heat boiler to produce high
pressure
steam. A model of this process consisting of burner, waste heat boiler
and drum with controllers has been constructed. In the development of
this
model the theory of combustion and heat transfer is studied. The
shrink-and-
swell phenomenon, affecting the drum level dynamics, and the consequent
control problem is given special attention. Modeling is done in Omola,
an object-oriented modeling language, and simulation in OmSim. The
developed
plant model is simulated and the results are found in good resemblance
with the actual plant. However, no real validation has been made.

Manual Control of Unstable Systems
Student: Sabina Brufani
Advisor: Karl Johan Åström
Date begun: June 96
Document Number: 5576
Abstract:
Automatic control is increasingly used in mission critical
applications. The reason for this is the potential benefits and the
fact that control engineering is now able to deal with complex
systems. Control of high performance aircrafts is a typical example.
Considerable benefits can be obtained by having an aircraft that is
unstable in certain flight conditions and providing stability with a
control system. The unstable flight conditions typically include the
low speed conditions that occur during take off and landing. The
aircrafts have hydraulic actuators that saturate for large signals or
signal rates. Since the feedback loop is broken in saturation the
unstable states may diverge to situations which cannot be recovered.
The presence of a pilot is yet another complication because the pilot
may also drive the system unstable through manual control actions.
Design of control systems for such situations is a significant
challenge. Aircraft manufacturers have encountered severe difficulties
because of this problem which has led to severe delays of projects.
The design of control laws for unstable systems that make it
impossible for the pilot to drive the system unstable while
maintaining good handling qualities is a challenging problem. The goal
of this thesis is to develop insight into this problem. A strongly
simplified case that captures the key elements of the problem is first
solved to get some insight. This shows that it is possible to develop
a hybrid strategy which has interesting problems. A more realistic
problem is simultaneous stabilization and control of the pivot of an
inverted pendulum. This problem is nice because it also allows easy
verification in the laboratory. The problem is investigated and
control strategies are designed by combining several different
strategies using the hybrid approach. The properties of the strategies
are illustrated by simulation. Finally we make a preliminary attempt
at applying the ideas to the flight control problem. The conclusion of
the work is that the approach taken appears promising and worthy of
further studies.

Control of an Oscillatory System
Student: Mikael Danielsson
Advisor: Karl Johan Åström
Advisor: Anders Wallen
Date begun: September 1996
Document Number: TFRT-5575
Abstract:
Systems with structural resonances are difficult to control
if fast responses are required. Rapid changes in the control signal
may excite the resonant modes. In digital control with zero-order-hold
sampling there will be very rapid changes in the control signal. A way
to deal with the problem is to use predictive first-order-hold
sampling instead. The control signal is then linear between the
sampling instants. This thesis investigates trade-offs in control of a
typical oscillatory system. PI, PID and state feedback controllers are
examined analytically or by simulations with a model of the considered
system. A comparison is also made between zero-order-hold and
predictive first-order-hold sampling.

Document Number: TFRT-5574
Abstract:
For a process with random time delays, it is possible to
find the t optimal control law with dynamic programming. This control
law is complicated and is therefore of interest to find simpler
suboptimal controllers. The simplest one is the standard
LQG-regulator that ignores the varying time delays. It appears however
that this controller has bad stability properties or give bad
performance. In the thesis two suboptimal controllers are given, which
are compared with the optimal controller in some examples.

Advisor: Karl-Erik Årzen
Industrial Partner/Sponsor: ABB Network Partner
Date begun: Augusti 1996
Document Number: TFRT-5573
Abstract:
The Java programming language promises to be platform
independent. This feature makes graphical user interface (GUI)
development
in Java Interesting. The problem addressed in this paper is whether
Java can be used as a core in a new man-machine interface for power
control systems.
In order to get an answer to this problem the main objective of the
thesis
has been a evaluation of the Java-technology based on the building of a
prototype editor/viewer application. The editor part should allow
design of
control pictures based on information supplied by a real-time control
system.
The result is a fully functional editor/viewer application that can be
down-loaded from any WWW-browser, that supports Java. The prototype has
been
built using the OMT (Object Modeling Technique) method. The prototype
supports multiple documents, i.e., many editor and viewer windows.
There is a possibility to connect picture elements to a real-time
database for information updating. Control pictures generate their own
Jawa code,
they can be zoomed and panned, and the design is prepared for
information
zooming. The development tool used, Symantec Cafe, as well as some Java
performance related questions have also been investigated.

Speech Coding Using Orthonormal Basis Functions
Student: Sven Hedlund
Advisor: Björn Wittenmark
Advisor: Brett Niness (Newcastle)
Date begun: September 96
Document Number: TFRT-5572
Abstract:
Vocoders are coders that are designed to encode human speech
efficiently by using analytical models of the human vocal system. The
process of encoding involves dividing speech audio into many short
segments, then finding the parameters that cause the model to generate
the closest approximation to the sound in each segment. When using
linear predictive coding, LPC, compression is accomplished by modeling
the speech signal in each segments as an AR process and encoding the
model parameters rather than the speech. Decoding consists of sending
the parameters to the model to recreate the sequence of audio segments.
The adaptive all-pole filter used for linear prediction approximates
the true physical configuration of the human vocal tract, but with the
nasal tract left out. The contribution from the nasal tract suggests
the need for a pole-zero model instead of the conventional one. In
this report, we try to improve the traditional LPC by adding fixed
zeros to the vocal tract filter. Since the zeros are fixed, they will
not increase the parameters needed to represent the model. Experiments
that are made to determine how successful these ideas are when it
comes to perception by the human ear (i.e. sample, code, decode and
listen), show that one can not achieve significantly better speech
quality with any configuration of the added zeros.

Performance Improvement of PI-Control Using Nonlinear
Feedforward
Student: Bernd Trageser
Advisor: Karl Johan Åström
Advisor: Mikael Johansson
Date begun: September 1996
Document Number: TFRT-5571
Abstract:
Processes whose dynamics include large time delays have poor
control performance and slow responses to set-point changes. The aim of
this thesis is to improve the set-point response by augmenting standard
feedback control with a nonlinear feedforward. The feedforward
approximates the input-output characteristics of the plant. It can be
realized as an
universal function approximator such as a neutral network. In this way,
the feedforward directly computes the control required to obtain the
desired output in steady-state. A standard PI-controller is used in the
feedback loop to force the control deviation to zero, taking into
account
the effects of model uncertainties, load disturbances and disturbances
to the controlled variable. The same method can be used to include
feedforward from measurable disturbances. Methods for automatic tuning
of the PI-controller and the nonlinear functions are presented. The
PI-controller can be tuned by standard automatic-tuning experiments,
while the nonlinear feedforward compensation is learned through a
series
of closed-loop step-response experiments. This gives a simple and
automated
way of designing nonlinear feedforward compensators. The power of the
proposed method is illustrated by a number of simulations.

Abstract:
Increasing speed of paper machines, increasing quality standards
and high prices on pulp have increased the demand on the automatic
control
of the paper machines. The objective is to keep uniform basis weight
and
paper ash in production of a specific quality and to minimize the time
spent in changing qualities. Different proposals of rebuilding the
machines
and changing the structure of the controlling systems is of interest.
At
evaluation of different proposals in the perspective of automatic
control
is a simulation tool valuable.
A model of PM2 at Stora Nymölla AB has been brought
forward and
a simulation
tool has been constructed in simulink. The physical part of the machine
has been modelled. Concentrations are modelled dynamically and flows
are
modelled stationary. Identification of the real process has been made
to
determine the dynamic characteristics.
The model can with good results be used to test and evaluate
different
strategies of automatic control and with some restrictions be used to
evaluate rebuildings.

Modelling and Simulation of Sound Effects in Mechanical
Systems

Advisor: Hilding Elmqvist
Industrial Partner/Sponsor: Dynasim
Document Number: TFRT-5568
Abstract:
Facilities to present simulation results as animations on the Internet
have been developed. They can take simulation results from
the modeling and simulation environment Dymola and convert them to
a Virtual Reality Model Language (VRML) representation, which is the
new Internet protocol for displaying three
dimensional graphical worlds with sound effects.
Mathematical models for sound has been developed in Dymola.
The model for a string gives good results. However, it is much worse to
model a membrane. Sound models must have high
bandwidths, which require fine discretizations, which make the models
large and complex. Furthermore, sound interacts in complex ways
with the environment on its way to our ears. Filters that
compensate for the effects that are introduced during the
propagation of the sound from the source to the receiver have been
developed with good results. Software to output a general variable to
a sound-card under Windows has been developed.
The VRML has shown to be a great tool to model advanced
virtual
reality scenes including both sound and animation. In combination with
Dymola, VRML can be used to present dynamic
behavior including both animation and sound.

Document Number: TFRT-5567
Abstract
Stability and performance properties of a wind power plant are
analyzed.
In particular, the nonlinear effects of time-varying wind are
considered.
The stability analysis makes use of the Nyquist theorem, the Circle
Criterion,
and a generalization for periodic perturbations. The robust performance
analysis is done by optimization of linear matrix inequalities.
The stability was not found to be a problem, but the specified
performance was
difficult to prove.

Catalytic Reduction in the Ship Engines
Student: Torbjörn Aukland
Advisor: Per Holmström (ABB Fläkt Marine AB)
Advisor: Tore Hägglund
Document Number: TFRT-5565
Abstract
Recent years intensive measures of land-based emissions have increased
the share contributed from ships and other marine activities. The main
problem here is the nitrogen oxides emitted from todays fuel-optimized
diesel engines used by the majority of ships.
ABB Fläkt Marine is one of the very few companies
that provides
a solution
to emissions on nitrogen oxides. This is made with a technique called
Selective Catalytic Reduction using a substance, urea, which is
injected
into the exhausts to react with the nitrogen oxides in the reduction
catalyst
to form water, nitrogen and carbon oxide. The amount of injected urea
into
an exhaust pipe is controlled by measuring the momentarily load of the
engine. however, the optimal injection rate tends to drift slowly over
longer periods of time causing the actual injection rate to be either
too
low or too high. The adjustments of these trends have so far been made
manually by the company's service engineers, but with just a few more
plants
of this kind installed on ships around the world this would soon become
too
time consuming.
The purpose of this master thesis project has therefore been
to
suggest how
these trend adjustments could be carried out automatically. The
measurements,
mainly made on a ferry between Sweden and Denmark, show a very
different
dynamical behavior of the catalyst depending on whether the actual
injection
rate is too low or too high. They also show that variations in the
engine's
load have to be taken into consideration in some way during the
adjustments.
The suggested method uses time series analysis and prediction while
searching for the optimal injection rate.

Control of Roling Missile based on Measurement Information
from
Accelerometers
Student: Stefan Delin
Advisor: Johan Nilsson
Advisor: Ola Rönn (Bofors AB)
Sponsoring organisation: Bofors AB
Document Number: TFRT-5564
Abstract
This report is a study on placement of accelerometers in a rolling
missile.
A Kalman filter is used for estimation of some states of the rolling
missile.
The rolling angle is assumed to be known. The states are fed back to
give
the missile desired dynamics. Reference signals in the form of desired
accelerations are also introduced.
The report shows that one transverse measuring accelerometer
gives
enough
measure information to make estimation of the states needed for
feedback
possible. The estimation errors are only slightly lower if two
transverse
measuring accelerometers, placed perpendicular against one another, are
used
instead of one. Along the axis of symmetry of the missile there is an
interval,
in the front of the missile, where accelerometers should not be placed
due to
poor estimation. Bias errors in the accelerometers are efficiently
eliminated by bias estimating states. Turbulent wind must be modeled in
the Kalman filter
to get good estimation of the angle of attack and the side-slip angle.
In the
controlled missile the gyro-coupling, due to the roll of the missile,
is low.
The small effects that are left of the gyro-coupling can be further
reduced
with suitable controllers. Reference signals can be introduced in the
controller by feedforward of the states and control signals from a
filtered
reference signal. The feedforward can be done static without
considerable
deterioration of performance.

The Effect of Friction on Stabilization of an Inverted
Pendulum.
Student: Carl Fredrik Abelson
Advisor: Henrik Olsson
Advisor: Karl Johan Åström
Document Number: TFRT-5563
Abstract
This thesis investigates frictional effects on the stabilization of a
rotating inverted pendulum. Because of friction, limit cycles arise
when trying to stabilize the inverted pendulum. The stabilization is
done using
linear state feedback. For estimation of the states, Kalman filters are
used. Both real-time experiments and simulations are performed.
Two friction models are used, one classical with stiction and
Coulomb friction,
and one advanced and dynamic, the LuGre model. These are identified by
comparing limit cycles from the real process with limit cycles obtained
through simulations. Since the inverted pendulum is an unstable process
with fast dynamics, it is sensitive to parameter changes, and thus it
is
difficult to get good results. Model-based friction compensation is
also
tried. This results in reduced limit cycles.

Abstract
Input saturation and rate limitations are important, particularly for
unstable systems. The impact of a saturation and a rate limiter on a
plant
controlled with a PID controller is one problem. Anti-windup techniques
provide good solutions for systems with saturation but unfortunately
they do not work so well for systems with rate limitations.
Modifications
of the conventional anti-windup schemes re presented to overcome these
problems. A second problem deals with the phase lag induced by rate
limiters and several filters are presented and compared showing
different
kind of performances for each one. Analysis shows that no filter is
superior in all respects. The third problem deals with unstable multi
variable
systems. It is based on a linear model of the pitch motion of the
aircraft
JAS-39 Gripen. Modern fighter planes have highly unstable dynamics and
the
limited forces produced by the aerodynamic surfaces must match
diverging
actions caused by the intrinsic aerodynamic instability. Several
techniques
are used to design a controller that improves the handling qualities of
the
plane while avoiding that the pilot looses control of the plane. Hybrid
control has been implemented to provide smooth transition between a
normal
flight condition and a critical one and appears to be a promising way
to
deal with this kind of problems. Hybrid control can also overcome the
nonlinear behavior of a real airplane at high angles of attack.

Comparison of two Friction Models
Student: Magnus Gäfvert
Advisor: K. J. Åström
Document Number: TFRT5561
Abstract:
Friction modelling is a delicate problem which poses several challenges
to
control engineers. This work focuses on two recent models which
describe
friction with nonlinear dynamical systems: The Lugre model, and the
model
of Bliman & Sorine.
Comparisons are made concerning friction phenomena captured,
computational
issues, identification of model parameters and behavior at
zero-crossing of
the velocity. Properties are illustrated by simulations. New results on
stability and passivity for the Lugre model are presented. Experiments
are
carried out to validate the models. Limit cycles are investigated by
describing
function analysis. The impact of a dynamic friction model on friction
induced
limit cycles is discussed.
Both models give reasonable results in describing function analysis,
and it is
concluded that dynamic models are superior to static models when it
comes
to reproducing limit cycles. The Lugre model exhibits a richer behavior
in
terms of friction phenomena. The Bliman & Sorine model could be
problematic
to use because of poor damping properties. The damping problems for the
Bliman & Sorine model turns out to affect overall model
behaviour
in a
complex way.
This work was in part carried out at Laboratoire d'Automatique

Modelling and Control of an Electric Arc Furnace
Student: Rui Pedro P.C. Paiva
Advisor: M. Johansson
Advisor: K-E Årzén
Document Number: TFRT-5560
Abstract:
In an Electric Arc Furnace (EAF), electrical energy is the main source
of power used when melting scrap. In order to optimize the power
consumption, the EAF must be properly understood. Also, since the main
source of power are the electric arcs, its electrical and thermal
properties
must be analyzed. The arc power depends on its length and it is
adjusted
by moving the electrodes. In order to maintain the desired power
levels,
efficient control of the electrode movements is required.
This thesis presents an object-oriented model of the EAF where
its
main
subsystems, namely the electrical system, the electrode positioning
dynamics
and the disturbances are analyzed separately. Furthermore, a fuzzy
P-like impedance controller, based on the model implemented, is also
presented.

Improvements of a PID Controller
Student: Edith Dufrene
Advisor: L. Pernebo
Advisor: K.J. Åström
Advisor: T. Hägglund
Document Number: TFRT-5559
Abstract:
This paper describes three improvements for a PID controller. These
improvements have been created with SattLine, which is an
object-oriented,
distributed process automation system developed by Alfa Laval.
These improvements are a compensator for static friction in
control
valves, an interpolation between the PID values when the system is non
linear and the creation of a table to save different gain schedules.
The two first improvements have been tested in simulation and
in a
plant, Danisco Sugar, the third one has just been tested at Alfa Lval.

Document Number: TFRT-5557
Abstract:
Industrial robots are used/configured/programmed by several different
types of users/programmers. The control system should preferably
expose a uniform view for each programming situation. Such views were
defined by the Open Robot Control (ORC) architecture, developed within
the department in an earlier project.
This project will refine and evaluate some high level robot
programming principles. First, earlier prototype implementations will
be merged together to a more complete system. Secondly, the low-level
control will be verified for an available ABB IRB-6 robot. Third, the
system will be improved to allow robot programming languages and
interpretors to be exchanged at run-time. It should also be possible
to introduce new control loops based on externals sensors. The goal is
to let the robot perform contour following; user-friendly programmed
using the developed features.

Konzeption und Realiziering eines Echtzeitbetriebssystems

Systems). The Master Thesis is in German.
Student: Johan Hellquist

Advisor: K. Nilsson
Advisor: U. Rembold
Advisor: R. Johansson
Document Number: TFRT-5558
Abstract:
In the control of mobile autonomous robots a number of static
control-architectures with their own characteristics, for example
classical hierarchic and parallel overloading (behavior-based)
control-architectures, can be found. Experiences have shown that the
control-architecture is as important as the control-algorithms and
that there is a need of combining and changing control-architectures
in run-time.
A structure-adaptive control architecture alters the
information-
and control-flow in run-time in order to obtain a control-structure
which
changes depending on the actual mission and states.
The above concept is supported by the
real-time-robot-operating-system
CAIC (Cooperative Architecture for Intelligent Control). CAIC was
implemented
and used to control two mobile miniature manipulators (Khepera-robots).
The two robots were able to cooperatively grip, raise and transport a
rectangular object (the spacing-piece in the Cranfield Assembly
Benchmark).
They communicated with local IR-communication to send command and
acknowledgments.

Abstract:
Industrial robots are used/configured/programmed by several different
types of users/programmers. The control system should preferably
expose a uniform view for each programming situation. Such views were
defined by the Open Robot Control (ORC) architecture, developed within
the department in an earlier project.
Another development is the so called Pålsjö
system, a DDC
package
supporting rapid control prototyping. Control blocks are expressed in
an
imperative block definition language, using a C/C++ style for pure
computations. A run-time system supports interactive creation and
execution of control blocks.
This project will refine and evaluate some low-level robot
control
and
programming principles, and a GUI to the Pålsjö
system will
be outlined
and possibly implemented. First, the current version of the robot
control
system (based on an available ABB IRB-2000 robot) will be extended
concerning the real-time control, the supervision of the system, and
the
control engineering tools. That will allow control experiments to be
performed in a safe and efficient way. Secondly, the low-level control
will be improved and tuned using the tools developed. The goal is to
let
the robot perform a force control task, or to stabilize an inverted
pendulum mounted on the end-effector, using the
Pålsjö
system.

Application of Subspace-based Methods of System Identification
Student: Jonas Ekblad (F91)
e-mail: f91je@efd.lth.se
Advisor: Rolf Johansson
Date begun: 1 Nov 1995
Document Number: 5556
Abstract:
A major drawback with the ARMAX model approach to identification
of multi-variable systems is the difficulty of model class selection
and overparametrization of fractional models which, in turn,
precludes the use of many numerical optimization techniques
to solve an identification problem A major obstacle is that
there is no unique parameter set that corresponds to an
input-output relationship, hence there are no unique convergence points
of optimization.
Subspace-based methods offer an alternative approach but
the methods are prone to error for low signal-to-noise ratios.
An experimental evaluation of noise sensitivity of subspace-based
identification applied to postural dynamics is considered.

Abstract:
The four degree of freedom (4 DOF) controller provides an approach for
design of integrated control and diagnosis systems. The problem is
formulated on standard interconnection form and can be attacked with
different control design methods, e.g., $Hinfty$ or $H2$ control.
This thesis has investigated the 4 DOF controller in
combination
with
$Hinfty$ and $mu$-design. Two problems have been studied, a literature
example and diagnosis of a simulated inverted pendulum. Special focus
has been put on the selection of weighting filters.

Speed Control of a Switched Reluctance Motor

Advisor: Christer Andersson (Emotron)
Industrial Partner/Sponsor: Emotron
Date begun:
Document Number: TFRT-5551
Abstract:
This thesis gives an introduction to the switched reluctance
motor. A model is developed in Simulink to investigate its nonlinear
characteristics. A controller is designed for the Simulink model. The
major concern for the controller is to obtain
a smooth torque. Normally the current is measured for control,
but in this case the current is not used, which means that an inner
loop is lost. The following gain scheduling principle for the speed
controller is proposed. Operating points for the speed and the
torque are defined, around which the system is linearized. Two
parallel controllers are implemented. A shape controller to minimize
the torque ripple, and a PI-controller to handle reference changes
and load disturbances. The shape controller produces a voltage shape
at a level determined by the PI-controller. The parameters of the
controllers are tuned according to the current operating point.

Adaptive Control of Systems with backlash
Student: Mattias Grundelius
Advisor: Karl Johan Åström
Industrial Partner/Sponsor:
Document Number: TFRT-5549
Abstract:
Backlash is common in mechanical and hydraulic systems. It severely
limits
the overall system performance. Many mechanical solutions have been
developed to overcome backlash, for example by using spring-loaded
split
gear assemblies or dual motor systems. These mechanical solutions can
satisfactorily handle the backlash problem but they give rise to other
problems like decreased accuracy and reduced control speed. They are
also more expensive, they consume more energy and they increase the
weight of the system. Therefore it would be very nice to find ways to
do backlash compensation that is not based on mechanical devices.
In this thesis it is attempted to approach the problem by adaptive
control.
Two different types of backlash compensations are examined; one linear,
phase lead compensation, and one nonlinear, backlash inverse. The
nonlinear backlash compensation gives better performance and is used in
the controller. The parameter values in the backlash inverse are
crucial
to the control performance and they need to be estimated if the
backlash
is unknown or varying. Two different schemes for estimating the
backlash
parameters has been considered, a model reference adaptive system and a
recursive least squares estimator. Beth methods require that the state
of the backlash (i.e. if it is in the dead-zone or not) is known. The
recursive least squares estimator is used in the adaptive controller
because it converge faster. The recursive least square estimator is
expanded so that the plant parameters can be estimated too. The
adaptive controller is tested by simulation on a second order plant
with known or
unknown parameters and an unknown backlash acting on the input of the
system. The simulations show that both the backlash and the plant
parameters can be estimated if you know the state of the backlash.

An Experimental Platform for DC-cable Interaction with Ship
Steering
Student: Staffan Nilsson
Advisor: Magnus Akke (Sydkraft AB)
Advisor: Anders Rantzer
Industrial Partner/Sponsor: Sydkraft AB
Date begun:
Document Number: TFRT-5546
Abstract:
HVDC (High Voltage Direct Current) cables are often used to transmit
electrical power between two areas separated by water. When a ship,
equipped with a ship steering automatic pilot containing a magnetic
compass, passes such a cable it will deviate from its intended course
and may even follow the cable.
The objective of this final master thesis was to build an
experimental
model. This model should be used to verify simulations of ships passing
a HVDC cable. It includes a radio controlled boat, an automatic pilot,
a magnetic compass and a position monitoring system. Some full-size
exerpiments
have been performed, but they were very expensive. This is why an
experiment
model would be most appreciated.
We want an automatic pilot which controlled the boat heading
using a
magnetic compass as the input. After having tried different solutions
for
the automatic pilot we chose a model which consisted of two micro
controllers situated on the boat.
The position monitoring system uses pulses of audible sound.
Four
microphones detect the sound, each with a certain time delay
proportional
to the distance from the boat. From the differences in time delay the
boat position can be calculated.
Experiments show that the model behavior was as expected, the
boat
deviated
from its course and in the worst cases followed the cable.

Prototype Implementation of the PLC Standard IEC 1131-3
Student: Martin Öhman, Stefan Nilsson
Advisor: Karl Erik Årzen
Industrial Partner/Sponsor:NUTEK
Document Number: TFRT-5547
Abstract:
IEC 1131-3 is a standard for programming languages used in programmable
controllers (PLC). it consists of four language paradigms, two
graphical
and two test based, and sequential function charts (SFC).
This master thesis describes a prototype implementation of the
Function
Block Diagram language combined with SFC. Different function blocks and
SFC elements are implemented as a number of classes and code is written
to execute them.
We have spent most of the project on issues of execution order
which
are
not well specified in the standard. The objects are sorted into lists
and executed. Algorithms for local or global sort are implemented and
evaluated. We have also discussed other execution methods.
The implementation is done using the graphical and object
oriented
expert system G2 as a prototype tool.
