摘　　要：本文建立了四相无刷直流电动机的数学模型,分析此类电机转矩脉动的形成原因,采用重叠换相的控制方法来抑制转矩脉动,最后在Matlab/Simulink软件下搭建模型,对该方法的应用进行了系统仿真,仿真结果表明该方法在四相无刷直流电机中取得了很好的效果,通过调整重叠换相角能够有效的抑制转矩脉动。The mathematical model of the four-phase brushless DC motor was introduced in this paper. The forming reason of torque ripple of this motor was also analyzed. The overlapping commutation technique was used to inhibit torque ripple was applied in this motor. Making a system simulation using this method via matlab/simulink. The simulation results show that the method achieving good results in the four-phase brushless DC motor,and the torque ripple can be inhibited effectively by modifying the angle of overlap...
