Simulation Study of Vector Control of Permanent Magnet Synchronous Motor with Fuzzy PI Controller

There are several drawbacks to the traditional proportional-integral (PI) control of permanent magnet synchronous motors (PMSM), including its poor flexibility and heightened sensitivity to outside disturbances. To solve these problems, this paper uses a fuzzy PI controllers to augment the PMSM vector control model. Firstly, based on the mathematical model, the corresponding PI controller is established; on this basis, the fuzzy rules are used to adjust the parameters of the PI controller in real time for the defect that the parameters of the PI controller cannot be automatically adjusted in real time operation of the motor, which leads to poor dynamic characteristics. When compared to regular PI controllers, these fuzzy PI controllers improve the system’s anti-disturbance performance and control precision.
