Abstract

The SRM drive operates over the entire speed range and provides low torque ripple with smooth transition between the control operations. The low torque ripple is achieved by controlling the firing angles through simple formulas so as to minimize the pulsations of the total current in the commutation region. The smooth transition is attained since the conditions that determine the firing angles of one operating mode are derived fr om the conditions of the other operating mode. This is important since the position precision is highly influenced fr om the motor torque ripple. The problem of highprecision position control in switched reluctance motor (SRM) drives is investigated in this paper. Advanced proportional–integral and Fuzzy proportional–differential controllers for speed and position controls, respectively are adopted. A gainscheduling technique is adopted in the speed controller design for providing high dynamic performance and precise position control. The SRM drive is modeled in Simulink environment and several simulation results are presented to validate the feasibility of the proposed control scheme.
