1. Study of vector control strategy on Interior Permanent Magnet Synchronous Motors
Magister-uppsats, Högskolan Väst/Institutionen för ingenjörsvetenskapSammanfattning : This thesis presents a comprehensive study of Direct Torque Control (DTC) for Interior Permanent Magnet Synchronous Motors (IPMSMs) evaluating its potential in high performance motor drive systems. The research begins with a literature review, looking into the fundamental principles of DTC, Pulse Width Modulation (PWM), Space Vector Modulation (SVM) and Field Oriented Control (FOC). LÄS MER
2. Continuous Control SetModel Predictive Control of Permanent Magnet Synchronous Motor
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : The thesis provides design methods for developing Continuous Control SetModel Predictive Control and Linear Quadratic Regulator for Interior mounted Permanent Magnet Synchronous Motor drive. The software for these controllers are implemented in the prototype motor at China Euro Vehicle Technology (CEVT) to estimate the computation time. LÄS MER
3. Efficiency Comparison between Two-Level and T-Type Inverter for 800 V Automotive Application
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : The falling cost of batteries, along with an increasing need to cut emissions, has spurred significant interest in the electrification of vehicles. In addition, as semiconductor devices have evolved, the research for electric vehicles with higher battery voltage has increased. LÄS MER
4. CURRENT OVERSAMPLING ANALYSIS FOR ADVANCED CONTROL OF ELECTRIC AC DRIVES
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : The main purpose of this thesis is to develop a sensorless control for a synchronous reluctance motor by using the slope measurement of the current ripple introduced by the Space Vector Modulation.The position estimation is performed at each Space Vector Pulse Width Modulation period and it relies on the estimation of current derivatives.

5. Sensorless algorithm for synchronous machines using current oversampling and PWM harmonics
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : Sensorless-controlled drives represent a solution drawing an increasinglyimportant attention for the benefits they entail. At the cost ofa slightly lower dynamics compared with the traditional drives, theyinvolve a reduction of the system costs and complexity and improvednoise immunity and reliability. LÄS MER
