Switched Reluctance Motor (SRM) has a very high potential for adjustable speed drive operation due to their cost-effectiveness, high efficiency, robustness, simplicity, etc. Now a days SRMs are widely used in automotive industries as traction motors in electric vehicles and hybrid electric vehicles, air-conditioning compressors, and for other auxiliary services. In this article, a novel super twisting sliding mode controller (STSMC) is proposed to improve the performance of an SRM for reducing the ripple in speed and torque. Initially, a novel Modified Electric Eel Foraging Optimization (MEEFO) technique is developed by incorporating a quasi-oppositional phase and its performance is compared with the conventional Electric Eel Foraging Optimization (EEFO) technique with four popular benchmark functions. Then, both MEEFO and EEFO techniques are implemented to optimally design PI, SMC and STSMC controllers to effectively control the speed of an SRM. The study is carried in three different scenarios such as during starting, during a torque change and during a speed change. Finally, performance of the SRM in real time is studied with OPAL-RT 4510 simulator. It is observed that MEEFO based STSMC exhibits significant improvements in effectively controlling speed of the SRM, as compared to its other proposed counterparts.
开关磁阻电机（SRM）因其成本效益高、效率高、坚固耐用、结构简单等特点，在调速驱动运行方面具有很高的潜力。如今，开关磁阻电机广泛应用于汽车行业，如电动汽车和混合动力电动汽车的牵引电机、空调压缩机以及其他辅助服务。在本文中，提出了一种新型的超扭曲滑模控制器（STSMC），以提高开关磁阻电机的性能，减少速度和转矩的脉动。首先，通过引入准对立相位开发了一种新型的改进电鳗觅食优化（MEEFO）技术，并将其性能与传统电鳗觅食优化（EEFO）技术在四个流行的基准函数上进行了比较。然后，分别采用MEEFO和EEFO技术对PI、SMC和STSMC控制器进行优化设计，以有效控制开关磁阻电机的速度。研究在三种不同的工况下进行，即启动过程、转矩变化过程和速度变化过程。最后，使用OPAL-RT 4510模拟器对开关磁阻电机的实时性能进行了研究。结果表明，与其他提出的对应方法相比，基于MEEFO的STSMC在有效控制开关磁阻电机速度方面有显著改进。
