Switched reluctance motors are a potential competitor to permanent magnet motors and induction motors for various industrial applications. The switched reluctance motors without permanent magnets have gained increased interest due to their simple structure, low cost, robustness, and high fault tolerance. However, the nonlinear characteristics caused by the double salient structure limit its wide applications. Advanced control techniques have been developed to suppress torque ripple, enhance anti-disturbance ability, reduce the switching frequency, expand speed range, and improve efficiency. The control strategies such as direct torque control and control algorithms like sliding mode control are two main approaches considered. Previous work only focuses on one side of control techniques. Thus, based on various control techniques proposed in recent years, this review classifies and summarizes their benefits and shortcomings. In addition, some essential trends in control development are presented and highlighted as future perspectives. [Display omitted] • The fundamentals including the SRM model and power converter are investigated and summarized. • Advanced control strategies of SRM are comprehensively illustrated and discussed. • The control algorithms including state-of-the-art control approaches with multiple control techniques are classified and analyzed. • Future perspectives of this emerging area have been pointed out.
