Direct Torque Control of 5-phase 10/8 Switched Reluctance Motor by Using Fuzzy Method

M. Reza Feyzi, Yousef Ebrahimi and Mahdi Zeinali

Abstract—A Switched Reluctance Motor (SRM) has several desirable features, including simple construction, high reliability and low cost. However, it suffers from large torque ripple and large noise. In addition, highly non-uniform torque output and magnetization characteristics lead to complication of the control system. Several studies have succeeded in torque ripple reduction for SRM using Direct Torque Control (DTC) technique. Compared to conventional methods including voltage control and current chopping mode control, DTC method has many advantages such as simple algorithm, less torque ripple and instantaneous response to the torque command. In this paper, DTC of a 5 phase 10/8 SR motor is proposed. Performance of the motor is studied through the computer simulation in Matlab/Simulink. The simulation results are compared to corresponding results of the same motor, controlled by hysteresis band method. The comparison results show that the proposed method results in a remarkable reduction in torque ripple for all levels of the motor torque without enforcing any drawbacks to the system performance, even in the transient conditions.
