1. Cross coupling in a two-axis control system for stabilized platforms
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : Inertial stabilized platforms consisting of a two-axis gimbal assembly are often modelled as two independent SISO systems, describing the dynamics of the elevation axis and the azimuth axis respectively. In reality the state of the elevation channel and the state of the azimuth channel affect each other. LÄS MER
2. Online Parameter Estimation of a Six- Phase Machine for Marine Application
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : In the recent decades, an increased interest into multiphase machines has developed due to certain beneficial properties they have over the standard three- phase machines. Proper modelling of a multiphase machine allows access to higher degrees of freedom given by the ability to control higher order harmonic frames. LÄS MER
3. Implementation of a Model Predictive Controller in a Spark-Ignition Engine
Master-uppsats, Linköpings universitet/FordonssystemSammanfattning : The propulsion of the spark-ignition engine has been investigated and developed during the past century to improve driveability, minimize fuel consumption and emissions, resulting in highly engineered and computerized powertrains. Well balanced engine maps containing coordinated set-points and model-based information sharing have solved the cross-coupling between different control loops. LÄS MER
4. Development of PMSM and drivetrain models in MATLAB/Simulink for Model Based Design
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : When developing three-phase drives for Electric Vehicles (EVs), it is essential to verify the controller design. This will help in understanding how fast and accurately the torque of the motor can be controlled. LÄS MER
5. Real-time stator resistance estimation for electrical drives : a control perspective
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : The automotive industry is in the middle of a rapid transition towards electrical machines. This transition leads to a higher interest in electrical machine management. In this thesis a stator resistance estimation scheme for field oriented controlled motors is proposed and tested in both simulations and experiments. LÄS MER
