摘要

在无刷直流电动机驱动中，转矩脉动一直是个问题。转矩脉动特别在换相期间显著，主要是由换相电流不相等但相反以及反电动势相移引起的。本文提出了一种带反电动势移相误差补偿器的恒带磁滞电流控制器，用于无刷直流电动机，以减小整体转矩脉动。详细阐述了所提出的技术，并分别通过Matlab/Simulink仿真和实验结果验证了其性能。

Overall Torque Ripple Reduction by Constant Band Hysteresis Current Controller with Back EMF Phase Shift Error Compensator in BLDC Motor Drive

Torque ripple is always problematic in BLDC motor drive. The torque ripple particularly during commutation period is significant and caused mostly by nonequal but opposite commutation phase current rate as well as back electromotive force (EMF) phase shift. In this paper, a constant band hysteresis current controller with back EMF phase shift error compensator for the brushless DC (BLDC) motor is presented to minimize the overall torque ripple. The detailed proposed technique is elucidated and the performance is verified via Matlab/Simulink simulation and the experimental results respectively.
