This paper considers the implementation of a current control method for switched reluctance motors (SRMs) and presents a novel approach to the accurate on-line modeling of an SRM drive. A simple autotuning technique for the SRM drives using a PWM controller is considered. Furthermore, conventional PI control and Internal Model Control (IMC) are considered to validate this method and present corresponding robust control analysis for the process. The control structures are comparatively analyzed using standard robustness measures for stability and performance. The proposed PWM controller is simulated and a hardware prototype is then implemented using digital signal processor control to evaluate the method using a 12/8, three-phase SRM. The experimental results of the SRM drive model validates the performance of the current loop.
本文考虑了开关磁阻电机（SRM）电流控制方法的实现，并提出了一种用于SRM驱动器精确在线建模的新方法。研究了一种使用脉宽调制（PWM）控制器的SRM驱动器简单自动调谐技术。此外，还考虑了传统的比例积分（PI）控制和内模控制（IMC）来验证该方法，并对该过程进行相应的鲁棒控制分析。使用稳定性和性能的标准鲁棒性指标对控制结构进行了比较分析。对所提出的PWM控制器进行了仿真，然后使用数字信号处理器控制实现了硬件原型，以使用12/8三相SRM评估该方法。SRM驱动器模型的实验结果验证了电流环的性能。
