1. Enhancing Servo System Performance : Robust Nonlinear Deadbeat Predictive Current Control for Permanent Magnet Synchronous Motors
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : The Permanent Magnet Synchronous Motor (PMSM, also known as the servo motor) is a crucial component within robotic servo systems. To optimally respond to the torque demands sent from the high-level motion controller, the PMSM current controller must track the reference with speed and precision. LÄS MER
2. Arbitrary motion Synthetic Aperture Radar
Master-uppsats, Lunds universitet/Matematisk statistikSammanfattning : Syftet med denna avhandling är att utveckla en ny metod för att producera bilder med syntetisk aperturradar (SAR), med utgångspunkt i scenarier med arbiträr rörelse vad gäller radarsensorn. SAR är en väletablerad metod för att skapa 2- eller 3-dimensionella radarbilder, som traditionellt sett antar att radar-sensorns rörelse är linjär och förutsägbar. LÄS MER
3. Iterative Evaluation and Control Methods for Disturbance Suppression on a High Precision Motion Servo
Master-uppsats, Linköpings universitet/Institutionen för systemteknikSammanfattning : Moore’s law states that the number of transistors in an Integrated Circuit (IC) doubles every two years. Ever-increasing performance in mask writing machinery is therefore required being the first step in the manufacturing process. Many factors affect the quality of the end product, with the motion control system playing an important role. LÄS MER
4. Gait screening using a mobile phone application : horse asymmetry levels and usability of a mobile phone application for gait analysis, during a long format FEI eventing competition
Uppsats för yrkesexamina på avancerad nivå, SLU/Dept. of Anatomy, Physiology and BiochemistrySammanfattning : Orthopaedic disorders are the most common reason for unplanned rest in the performing horse population. Locomotor disorders which slowly build up to clear lameness might be avoidable with easy access objective motion measurement devices. LÄS MER
5. Measuring the Pulse Duration and the Time-Dependent Polarisation State of Ultrashort Laser Pulses with the D-Scan Technique
Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/AtomfysikSammanfattning : Ultrashort laser pulses with time-dependent polarisation states have many applications, such as the generation of isolated attosecond pulses and the study of the optical chirality of molecules. In this project the polarisation gate, built from two quarter-wave plates of different orders, is thoroughly characterised in experiment and simulation. LÄS MER
