Nowadays, the studies about the brushless DC motor(BLDCM) control are mainly focused on motor state. However, it may also work in generator state. The control of BLDCM torque is generally achieved by controlling the motor current. The current hysteresis control(CHC) method can control the motor current directly, so the better torque control performance can be obtained. A CHC for BLDCM in motor and generator state is presented. CHC can not only complete commutation successfully but also reduce commutation to...

0引言无刷直流电机(Brushless DC Motor, BLDCM)因其较高的比转矩、控制算法简单、易于维护等优点,在机器人、航空航天、汽车、家用电器和医疗器械等领域得到了广泛的应用[1-3]。学者们对BLDCM的研究主要是关于以下几个方面:(1)减小换相区间的转矩波动[4];(2)减小不理想电动势?
