Fuzzy Adaptive Controller Design of Permanent Magnet Synchronous Motor for Electric Vechicle

This paper proposes a new adaptive fuzzy active disturbance rejection control design technique on permanent magnet synchronous motor (PMSM). Fuzzy logic control is applied to adjust the proportional coefficient of nonlinear proportional error control (NLPE). The extended state observer (ESO) is used to track and estimate the uncertainty of PMSM system including unmodeled dynamics, load disturbances and parameter perturbations. The control variable put into system can be obtained through subtracting the estimator of ESO from the output of NLSEF adjusted online by using fuzzy logic control and. The simulation results show that the proposed control strategy operates robustly under modeling uncertainty and external disturbances and has good dynamic performance.
