This project deals with the design of a sensorless Field Oriented Control (FOC) on a surface mounted permanent magnet synchronous generator (PMSG) for wind turbine applications. In order to be able to implement the control in laboratory, a 2.2[kW] machine is used. The FOC is first simulated in Matlab/Simulink, using the measured speed and position. A method for estimating the rotor position is investigated and also tested in simulation. The simulation results show good performance for both sensored and sensorless FOC. The sensored FOC is tested in dSpace and the results prove that the control is working. The position estimation method could not be implemented in laboratory. The main conclusions are taken in the final chapter.
