Identifiering och simulering av pappersmaskin (Identification and Simulation of Paper Machine)

Abstract:

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

Abstract:

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.

Catalytic Reduction in the Ship Engines

Abstract

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

Abstract

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.

Abstract

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.

Comparison of two Friction Models

Abstract:

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 de Grenoble, CNRS-INPG-UJF, France.

Improvements of a PID Controller

Abstract:

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.

An Open System for Robot Programming and Control

Abstract:

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 fur Strukturadaptive Regelsysteme. (Design and Implementation of a Real-Time-Operating-System for Structure-Adaptive Control Systems). The Master Thesis is in German.

Abstract:

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.

Experimental Robot Control and Programming

Abstract:

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.

An Experimental Platform for DC-cable Interaction with Ship Steering

Abstract:

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

Abstract:

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.
