This article develops a novel average torque control (ATC) scheme for switched reluctance (SR) motor on the basis of a brand-new microstep flux–current locus controller. The proposed ATC is based on the calculation of the average torque from the converted mechanical energy that can be illustrated as an enclosed area in a flux–current plane. It has the superior advantage that it is able to control the average torque over any arbitrary small-angle intervals, whereas the conventional ATC can control only the average torque for a whole stroke. In order to realize the proposed ATC, a flux–current locus controller, which consists of a hybrid flux controller and current controller as well as involve the microstep process, is introduced in this article. The flux–current locus of the energy conversion loop is controlled for the first time in the literature. With the locus controller, it is possible to achieve a better energy conversion ratio and the ATC. In order to verify both the proposed locus control method and the ATC for SR motor, detailed simulation results and discussion are provided.

基于磁通电流轨迹控制的新型开关磁阻电机平均转矩控制

本文基于全新的微步磁通-电流轨迹控制器，为开关磁阻 (SR) 电机开发了一种新颖的平均转矩控制 (ATC) 方案。建议的 ATC 是基于转换后的机械能的平均扭矩的计算，可以表示为磁通-电流平面中的封闭区域。它的优点是可以控制任意小角度区间的平均扭矩，而传统的ATC只能控制整个行程的平均扭矩。为了实现所提出的 ATC，本文介绍了一种磁通 - 电流轨迹控制器，它由混合磁通控制器和电流控制器组成，并涉及微步过程。在文献中首次控制了能量转换回路的通量-电流轨迹。使用轨迹控制器，可以实现更好的能量转换比和 ATC。为了验证所提出的轨迹控制方法和 SR 电机的 ATC，提供了详细的仿真结果和讨论。
