  1. In this paper, an integral sliding mode current controller (SMC) is proposed for mutually coupled switched reluctance motors (MCSRM) using asymmetric bridge converters aiming to achieve constant switching frequency and lower sampling rate. A generalized state-space model is built and then the design of a sliding mode controller along with the stability analysis of the closed-loop system are presented. The effectiveness of SMC is verified using simulation studies with a three-phase, sinusoidal excitation 12/8 MCSRM over a wide speed range. Compared to the hysteresis current control, the proposed SMC-based design approach demonstrates a comparable response in terms of currents ripples, the root-mean-square error of current and torque while achieving a constant switching frequency and lower sampling rate.
