Speed Control of Permanent Magnet Synchronous Motor

Abstract

This thesis studies the field-oriented control (FOC) for speed control of Permanent Magnet based Synchronous Motor (PMSM) over the entire speed range, which is the vector control method. The main concept of the FOC strategy is to decouple the stator current into a torque developing part and a magnetic field developing part. This will simplify the control of PMSM, and the whole structure will look like a DC machine. This project aims to obtain smooth control of the entire speed range, faster acceleration, and faster deacceleration of the PMSM. To get vector control of PMSM, a MATLAB/SIMULATION model must be prepared. After getting the desired result from the model, a different Simulink model is to be designed, ready to implement on hardware.
