1. Learning Model Predictive Control for Autonomous Racing : Improvements and Model Variation in Model Based Controller
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : In this work, an improved Learning Model Predictive Control (LMPC)architecture for autonomous racing is presented. The controller is referencefree and is able to improve lap time by learning from history data of previouslaps. LÄS MER
2. Sensor Array Optimization for Multiple Harmonic Sound Source Separation and DOA
Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Teknisk akustikSammanfattning : INTRODUCTION In the last years a lot of researches about source separation have been realized, like extraction of a signal of interest (vocal recognition application), identification of which source gives which sound (motor engine applications) or noise source characterization (environmental application). Most of these techniques for sound source estimation use the signal-subspace approach, where the number of emitting sources is determined by the multiplicity of the lowest eigenvalue of the correlation matrix.

3. Implementering av multivariabel reglering i DCS-miljö
Uppsats för yrkesexamina på avancerad nivå, Institutionen för systemteknikSammanfattning : Inom processindustrin finns en etablerad reglerhierarki där basreglering sker med PID-regulatorer och där avancerad, multivariabel styrning sköts av MPC-programvara. Steget mellan dessa två nivåer kan upplevas som stort. För mindre och snabba multivariabla processer undvikes helst en multivariabel ansats, med försämrad reglering som följd. LÄS MER
4. Closed Loop System Identification of a Torsion System
Uppsats för yrkesexamina på avancerad nivå, Institutionen för systemteknikSammanfattning : A model is developed for the Quanser torsion system available at Control Systems Research Laboratory at Chulalongkorn University. The torsion system is a laboratory equipment that is designed for the study of position control. LÄS MER
5. Subspace-based Identification of a Parallel Kinematic Manipulator Dynamics
Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknikSammanfattning : This thesis deals with the identification of the dynamics of a Parallel Kinematic Manipulator, namely the Gantry-Tau patented by ABB located in the Robotics lav at LTH, Lund. The approach considered for modelling is subspace-based identification of linear models, where measurements from the robot motion are used to estimate the unknown parameters in the models. LÄS MER
