摘要
利用Ｐｓｐｉｃｅ仿真软件，对具有正弦磁场的无刷直流电动机系统的波动力矩进行了仿真研究。由电机的绕组端电压、相电流及转速构造了波动力矩观测器，其输出信号反映了电机的波动力矩；波动力矩的闭环控制减小了电机输出力矩的波动，并给出了仿真结果。
The digital simulation of ripple torque of sine-wave brushless DC(BLDC) motor system is studied by the Pspice software. According to the mathematical model of the BLDC motor system,an observer of ripple torque is construced whose inputs are phase voltages, phase curents and angular speed. The output of the observer stands for ripple torque. The closed-control of ripple torque can restraint the ripple torque. The simulation results are supplied at last.
