1. INDUCTIVE RAILWAY SWITCH POINT HEATING : Improved control algorithm and phase compensation analysis for an inductive turnout heating system, and comparison with a resistive heating system
Uppsats för yrkesexamina på grundnivå, Mälardalens universitet/Akademin för ekonomi, samhälle och teknikSammanfattning : Railway turnout heating is essential during the winter because snow and ice can hinder the movement of the switch. In Sweden, heating has traditionally been done using resistive heating wires mounted to the stock rail, but the technology is outdated and generally exhibits low efficiency and performance. LÄS MER
2. Strömmätsystem för 10 000 Ampere : Enligt Rogowskiprincipen
M1-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomiSammanfattning : På RISE (Research Institutes of Sweden) finns en betydande kalibreringsverksamhet där avdelningen för högspänning önskar utöka sin strömmätningskapacitet för AC strömmar vid kraftfrekvens upp till 10 000 A. Syftet är att med hjälp av Rogowskiprincipen bygga en mätrigg för kalibrering av strömtransformatorer i fält. LÄS MER
3. 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
4. Adaptive Rolling Radius Estimation
Master-uppsats, Linköpings universitet/FordonssystemSammanfattning : Tire tread health is essential for safe operation of a passenger vehicle. Worn out tires significantly increases the risk of traffic accidents and hydroplaning. This thesis investigates the possibility to detect tire tread wear by estimating the effective rolling radius of a tire. LÄS MER
5. Electrical Impedance Profiling of Plants, Coffee and TREO
Uppsats för yrkesexamina på grundnivå, Uppsala universitet/Signaler och systemSammanfattning : The aim of the project was to investigate the possibility of using low-cost hardware to monitor plant health, measure the impedance of water containing dissolved substances at different concentrations, and observe how the plant impedance is affected compared to auxiliary measurements of soil moisture, ambient light, humidity, and temperature.To measure impedance, we used electrical impedance spectroscopy which gives the impedanceacross a spectrum of frequencies.
