Abstract
Aiming at the shortcomings of torque ripple and flux ripple in the traditional direct torque control of permanent magnet synchronous motor (PMSM), as well as the problems of speed overshoot, this paper improves the PI controller of the speed loop and proposes a method based on Fuzzy-PI controlled PMSM direct torque control strategy. Simulation using MATLAB/Simulink verifies the feasibility of the Fuzzy-PI speed controller's permanent magnet synchronous motor direct torque control strategy, and compares with the traditional DTC permanent magnet synchronous motor to demonstrate the superiority of the proposed scheme, which is effective It reduces the pulsation of torque and flux linkage and suppresses the overshoot of speed.
