Based on the analysis of the principle of torque ripple with commutation time for brushless DC motor, this paper proposes a method to restrain commutation torque ripple. This method is an improved predictive current control. First, an expression is built about the torque ripple during commutation time. After analysis, the non-commutation phase current is related to torque ripple. Then, a kind of control strategy is designed. A controller is designed with improved predictive current approach to restrain the torque ripple. Next, the model and controllers are implemented in Simulink environment and numerical simulations are performed. Finally, in order to compare the performance of the proposed controller, experiments on other regular controllers are represented on PWM-ON modulation. The designed controller demonstrates much better performance than that of regular PWM-ON modulation controller under tests. Meanwhile, the effect of simulation indicates that the controller is adaptive for speed variation.
