A Fuzzy PI Speed Controller based on Feedback Compensation Strategy for PMSM
نویسنده
چکیده
in order to solve the problem of robustness or antidisturbance of the traditional PI speed controller in the permanent magnet synchronous motor. A fuzzy PI speed controller based on load torque feedback compensation is proposed for the permanent magnet synchronous motor. The combination of fuzzy PI control strategy and load feedback compensation method can enhance the robustness and disturbance rejection of the speed loop. According to the validated results of simulation and experiments, by using this PMSM speed controller, the robustness of the system speed control was enhanced markedly, and the capacity of antidisturbance was also improved significantly. Keywords—permanent magnet synchronous motor(PMSM); Fuzzy PI; torque feedback compensation; anti-disturbance
