【摘要】：整距绕组分块转子开关磁阻电机具有单位铜耗下输出转矩大、损耗低等优点,但转矩脉动大。本文采用余弦TSF控制法即通过控制电机各相电流产生的转矩分量使得低速时整距绕组分块转子开关磁阻电机的输出转矩脉动降低。针对电机转速升高后,由于实际相电流不能跟踪参考相电流,以及关断区间的电流不可控导致电机转矩脉动增大的问题,提出增大或减小其他相的相电流进行补偿的转矩控制策略并进行了分析。仿真和实验结果表明,该电流补偿策略的转矩分配控制法可有效抑制整距绕组分块转子开关磁阻电机的转矩脉动。
[Abstract]:The whole distance winding block rotor switched reluctance motor (SRM) has the advantages of large output torque and low loss per unit copper consumption. But the torque ripple is large. In this paper, the output torque ripple of the switched reluctance motor with integral winding block at low speed is reduced by using cosine TSF control method, that is, by controlling the torque component produced by each phase current of the motor. When the speed goes up. Because the actual phase current can not track the reference phase current, and the current in the turn-off section is not controlled, the torque ripple of the motor increases. The torque control strategy of increasing or decreasing the phase current of other phases is proposed and analyzed. The simulation and experimental results show that the torque control strategy is effective. The torque distribution control method based on the current compensation strategy can effectively suppress the torque ripple of the switched reluctance motor with integral winding.
