Permanent magnet synchronous motors in electric vehicles are gaining more and more attention because of its high performance and high torque to inertia and high power density. PMSM Motor should operate in four quadrant operation at different driving characteristics the torque speed characteristics of the motor is observed. Battery and super capacitor is used for energy sources to the permanent magnet synchronous motor the design of electric vehicle is onboard charging system. Battery and supercapacitor are hybrid energy sources. PMSM motor is controlled by using field oriented control technique. Voltage source inverter is used to control the speed of the PMSMS motor at different frequencies. The control technique used for VSI is space vector control technique. Using MATLAB/Simulink.

Torque Ripples

This paper aims to reduce the torque ripples in the motor torque, reduce the total harmonics distortion in the motor currents and improve the dynamic response of the permanent magnet synchronous motor. To carry out this study, a modification model was used and compared to conventional model. The main control method used here is a field-oriented control. It was used to generate two decoupled currents control. With help of rotor position, these currents changing into three-phase reference currents. These reference currents were compared to the actual three-phase motor currents. The errors among these currents are introduced to hysteresis current controller to get pulses. These pulses used to drive the voltage source inverter which produces three-phase voltage to drive the motor under study. This technique suffers from some problems as high torque ripples, high total harmonics distortion, the dynamic response isn’t very high because at the beginning of the error and the deviation of the output signal becomes large. This is a conventional model. To overcome these problems, the hysteresis current controller was replaced by gain impedance. The output of this gain is the three-phase voltages. These voltages generate pulses through space vector modulation to drive the inverter to get suitable voltage for the permanent magnet synchronous motor. This modification has decreased the torque ripples and the THD in comparison to the conventional controller. To more improvement in the motor performance, one PI torque current controller and load torque estimator were used to damp the overshooting and decrease the rise time.
