说明：  　本文对于反电动势波形接近正弦的永磁无刷直流电动机,提出一种基于六个离散位置信号的自同步SVPWM 控制方法,用于抑制电磁转矩脉动。仿真和实验结果表明,该种方法比传统的120°导通控制方式更能有效地抑制转 矩脉动。
(This close to the sine wave of anti-EMF permanent magnet brushless DC motor, is proposed based on six discrete position signal from the synchronous SVPWM control method for suppression of electromagnetic torque ripple. Simulation and experimental results show that the methods than the traditional 120 ° conduction control method more effectively suppress torque ripple.)
