Abstract

Because of the nonlinear magnetic structure and time varying motor parameters, the traditional controllers like PI, PD and PID are insufficient in Switched Reluctance Motor (SRM) control. A strategy of hybrid Fuzzy-PI control for switched reluctance motors is presented in this paper. The strategy of fuzzy logic controller and PI controller is combined to realize the speed adjustment. The hybrid fuzzy-PI controller adopts fuzzy logic control when the speed error is big, and adopts PI control when the error is small. Simulation results indicate that this hybrid control strategy overcomes the steady state error of speed in classical fuzzy controller, and the paradox between the response time and overshoot of speed is managed. This system has a good anti-interference performance.
