Simulation and Modeling of 8/6 Switched Reluctance Motor Using Digital Controller

This paper investigates the problem of the position control in switched reluctance motor drives. Advanced proportional-integral (PI) and proportional-differential (PD) controllers for the speed and position control, respectively, are adopted. The parameters of the controllers are on-line fine tuned according to the load torque and rotor speed, for providing high dynamic performance and precise position control. In order to improve the set-point tracking of the drive performance, a low-pass filter is included in the position controller. The proposed four-quadrant control scheme is based on the average torque control method. The turn-on and turn-off angles are determined through simple formulas and the regulator is capable of maintaining the torque ripple at an acceptable level over a wide speed range. This is important since the position precision is highly influenced from the motor torque ripple. Experimental results of the switched reluctance motor dynamic response are presented to verify the theoretical considerations  Serials Publications, ISSN : 0973-7383
