Speed Control of IPM Motor Using Vector Control in Self-Synchronous Mode

Abstract

This paper presents a comparative study of different controlling techniques used for an IPM motor in electric vehicles and benefits of self-synchronous control using vector control of IPM motor. In self synchronous mode, the rotor speed is sensed using an encoder, the rotor speed and stator speed are then compared to generate an error signal. The speed of the stator field is changed according to the error signal using vector control, and the rotor track this synchronous speed. In this project, indirect vector control is done by generating command torque signals with the help of speed signals. The system is developed by using simulation model in SIMULINK.
