摘　　要：针对无刷直流电机转矩脉动的问题,提出了用带重叠换相模块的模糊PI控制器,来实现对无刷直流电机转矩脉动的抑制。给出无刷直流电机的数学模型,并分析了重叠换相方法及模糊PI控制器的原理。应用Simulink仿真模块,对无刷直流电机控制系统进行建模仿真,将仿真数据与实验数据进行对比分析,得出带重叠换相的模糊PI控制器可以更有效抑制转矩脉动,提高电机的控制精度,为以后实际应用提供了理论依据。Aiming at the problem of torque ripple in brushless DC motor, a fuzzy PI controller with the o- verlapping commutation module is proposed to restrain the torque ripple. The mathematical model of brushless DC motor is built, and the overlapping commutation method and the fuzzy PI controller princi- ple are analyzed. The simulation model of the brushless DC motor control system is established by Simu- link. The comparison and analysis of the results show that the fuzzy PI control system with the overlapping commutation phase restrains the torque ripple and improves the control precision more effectively so as to provide a theoretical basis for future practical application.
