摘要
在分析无刷直流电机运行原理的基础上,用Matlab/Simulink建立了无刷直流电机控制系统的仿真模型。为了减小无刷直流电机换相时出现的转矩脉动,采用了交流侧电流反馈的控制方法,仿真结果证明了该方法对换相转矩脉动具有较好的抑制作用。
In Matlab/Simulink,this paper built a simulation model of brushless DC motor（BLDCM） control system based on the principle of the BLDCM.Then used the control theory based on the exchange side current feedback for suppressing the torque during commutation,the validity of the proposed method to suppress the commutation torque ripple is verified by simulation.
