摘　　要：针对开关磁阻电机(SRM)换相期间存在较大转矩脉动的问题,提出一种基于变电流重叠角的转矩分配函数(TSF)用于SRM的直接瞬时转矩控制(DITC)。该方法利用换相期间电流特征,对电流重叠角的起始位置和结束位置进行检测,实现电流重叠角的实时计算,并根据电流重叠角设置SRM的关断角,对SRM各相转矩在换相期间进行合理分配。仿真和实验结果验证了该方法能够有效抑制转矩脉动。An improved torque distribution function （TSF） for switched reluctance motor （SRM） was proposed to re- duce torque ripple. According to the characteristics of current during commutation, the start position and end position of the current overlap angle were detected. The calculation of the current overlap angle in real-time was achieved for TSF. The phase torque of SRM was assigned reasonably. The simulation and experimental results show that the proposed method could reduce the torque ripple effectively.
