Modeling, simulation and control of switched reluctance motor drives

This paper presents the modeling, simulation and control aspects of four-quadrant switched reluctance motor (SRM) drives. The design of SRM drive systems must be focused on application based appropriate control and engineering solutions needed to overcome the practical issues. A complex model, incorporating the important dynamics of the SRM, is described for the physical motor simulation. A simpler, but quite accurate, model is presented for the SRM controller. Various practical limitations have been incorporated in the simulation model to make it closer to the experimental set-up. The SRM control parameters are chosen based on torque-per-ampere maximization requirement. Experimental results for a 1.0 kW switched reluctance motor obtained on a digital platform are presented along with useful guidelines for prototype implementation.
