Automatic Control

LTH best Master's thesis

Johanna Wilroth has been awarded the prize "LTHs Jubileumsstipendium 2020" for the best master thesis at LTH. In her thesis "Domain Adaptation for Attention Steering," Wilroth studied novel algorithms for improving the performance of hearing aids using EEG signals in combination with auditory input. The master thesis was done at the Department of Automatic Control, with Carolina Bergeling as main supervisor, in collaboration with the research center Eriksholm/Oticon in Denmark. The collaboration also involved the departments of Psychology and Mathematical Statistics at Lund University.

Abstract:

This project targets automating production steps where stud bolts are welded on a heat exchanger within allowed perpendicularly requirements.  Until now, this has been a manual process where an operator uses steel templates to position the bolts in the right place and manual welding guns to weld the bolts. The scope of this project is to create a digital model of a robot cell to calculate the coordinates of the bolts and weld them in the correct position in ABB software RobotStudio, and then test and verify it in a real cell with an actual ABB robot (IRB4600), measuring probe and welding equipment. During the simulation phase the first step was to decide which layout in the cell would be the best to optimise the measuring and welding process and design the gripper to hold the gun and the measuring probe. Then an algorithm to find the edges of the heat exchanger and calculate its center was designed. This point is used as the zero point for the coordinates of the stud bolts. In the verification phase the algorithm created for the simulation had to be optimised and adjusted to the real robot operation.

Welcome to KC4!

In 2020, we moved to temporary offices at KC4 in Kemicentrum. Here we will stay until 2023 while the M-building is being renovated. See "contact" (in About) for the new visiting adress.

Formula Student

The department has a collaboration with the Lund Formula Student team, who are developing a fully autonomous race car to compete in Formula Student events all across Europe. They are always looking for interested and talented team members. If you are interested in a wide variety of technologies such as neural networks, control theory, ROS, etc, please visit their website or contact them at: technical.driverless@lundformulastudent.se.
