Study on High-Grade Torque Control Strategies for Switched Reluctance Motor

The torque control strategy of the switched reluctance motor is divided three level cascade controllers: commutation strategy, torque controller and current controller. According to the three level cascade controller design strategy, this paper presents a high-grade torque control of SRM, which is based on fuzzy-neural inverse model and sliding mode current controller. Detailed simulation results show that SRM phase torque can follow a desired torque command, which results in a linear, decoupled and low ripple control of torque.
