Control of Torque Ripple of a Switched Reluctance Motor Based on Torque Vector Control

转矩脉动是开关磁阻电动机较为突出的缺点。文章基于电机的线性模型 ,提出了开关磁阻电动机转矩矢量控制策略。通过控制开关磁阻电动机各相绕组电流—位置曲线 ,在空间合成多个转矩矢量 ,以减小转矩脉动。仿真结果表明 ,这种控制策略不但控制简单 ,而且能够在低速下有效地抑制开关磁阻电动机转矩脉动。

Torque ripple is the main weakness of the switched reluctance motor(SRM).Based on the motor's linear model,a novel toque vector control strategy is presented.Multi-torque vector can be synthesized in the space by using the control of very phase current via rotor position.The simulation result shows that this control strategy is not only easy control but also can reduce the torque ripple of SRM.
