Speed Control Strategy of Switched Reluctance Motor Based on Fuzzy Autodisturbance Rejection
Due to the doubly salient structure of switched reluctance motor,the torque ripple is too large,and the system has serious nonlinearity,the given speed changes greatly,and the load disturbance is large.To overcome this problem,a fuzzy Active disturbance rejection control method was proposed.Combining the characteristics of switched reluctance motor and mechanical Equations of motion,a simulation model of doub-le closed loop system of switched reluctance motor was established.The speed loop used active disturbance rejection control technology and fuzzy control to adjust its parameters.The torque loop used direct instantane-ous torque control.Simulation experiments show that compared with traditional PI control,fuzzy active dis-turbance rejection control can effectively improve speed regulation performance,reduce torque ripple,and show good anti-interference ability.
