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.

Radar technology has developed a lot during the last years, which has resulted in smaller and cheaper radar modules. The new technology has led to many new areas of use, including for example detection sensors in the automotive industry. There are several types of radars, one common type being the frequency-modulated continuous-wave (FMCW) radar. The FMCW radar uses a frequency-modulated signal to sweep a frequency range. To do this, a voltage-controlled oscillator (VCO) that converts a control voltage to a sinusoidal signal can be used. Due to the VCO's temperature dependency and nonlinear mapping from voltage to frequency, it requires a closed-loop control system to work in a broad temperature range and to eliminate nonlinearities that have a negative effect on the radar's performance. This control system is often implemented with a phase-locked loop (PLL), which is an analogue control method typically implemented in an application-specific integrated circuit (ASIC). The objective of this master's thesis is to investigate the possibility to digitally control a VCO without using a PLL. The reason for this is to lower component costs by only using a microcontroller unit and no additional ASICs.

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:
