| Abstract: | According to torque ripple of brushless DC motor,in the paper,the different PWM modulation mode and overlapping commutation method is used to minimize torque pulsation when current commutation is considered.The Matlab/simulink is used to simulate this control system,the result shows that the limitation of commutation torque ripple is obvious,so these methods can minimize the torque ripple successfully. |
