Fuzzy PI Control Strategy of Permanent Magnet Assisted External Rotor Switched Reluctance Motor Based on Torque Sharing Function

In this paper, a new type of permanent magnet assisted external rotor switched reluctance motor (PMa-ERSRM) is proposed, which has the advantages of mixed excitation, segmented stator and external rotor. A new type of motor structure, mathematical model and Matlab modeling are introduced. According to the characteristics of the motor, the torque sharing function (TSF) is applied to the motor control, and the fuzzy PID control is introduced into the speed loop to improve the adaptability and robustness of the nonlinear system. Compared with the traditional control mode, the control strategy can significantly reduce torque ripple.
