Performance Analysis of High Precision Position Controlled Switch Reluctance Motor Drive

Abstract: The aim of this paper is to investigate the problem of high-precision position control in Switched Reluctance Motor (SRM) drives. Proportional-differential (PD) controller and Advanced gain scheduling proportional-integral (PI) controllers are adopted for position and speed controls, respectively. The control scheme used for the SRM drive operates over a wide speed range and supports the four quadrant operation and also provides low torque ripple at an acceptable level. The proposed four quadrant control scheme is based on the average torque control method. Low torque ripple is achieved by controlling the turn-on and turnoff angles through simple formulas so as to minimize the pulsations of the torque at the commutation intervals. The fine tuned PI controller parameters are online determined according to the load torque and speed of the rotor. In order to provide precise position control, a gain scheduling technique is adopted in the speed control design. A low-pass filter is included in the position controller to improve the set-point tracking and to prevent the impulse of the control signal. The SRM drive is designed and implemented in MATLAB/Simulink environment at different rotor positions and several simulation results are presented to validate the feasibility of the proposed control scheme.
