The Variable PWM Frequency Control Research for the Motor in Wheel

Abstract:

According to the characteristics that the motor in wheel is insensitivity of torque ripple, the impact of reducing PWM frequency on motor control is studied, and the phenomenon that the PWM frequency is limited by the lag angle of motor commutation. Then a variable PWM frequency control strategy according to rotate speed is proposed. Based on Simulink, the motor control model is built and the control strategy is verified by simulation. The result shows that the variable PWM frequency control significantly improves the performance of motor at low speed, with little toque ripple increased.
