Modeling and simulation of directly facing the torque ripple compensation method

According to two-phase conduction state of the motor´s three-phase six-star mode, the paper discusses and concludes the current commutation torque ripples generated by the mechanism. Being different from traditional parameter selection difficulties and torque ripple being not easy to control shortcomings to eliminate torque ripple methods, the paper proposes the compensation method for direct torque ripple. The paper builds in the mathematical model of torque ripple compensation in HPWM-LON modulation mode, and carries out modeling and simulation based on PSPICE. The simulation results show that the compensation method for direct torque ripple has good results, and has a very high value for study.
