Fuzzy ADRC Controller Design for PMSM Speed Regulation System
This paper introduces a new fuzzy active disturbance rejection control (ADRC) design technique into permanent magnet synchronous motor (PMSM) speed regulation system. By using fuzzy logic control, the proportional coefficient of nonlinear state error feedback (NLSEF) is timely adjusted to obtain the suitable feedforward control variable. The uncertain term of PMSM is tracked and estimated by using the extended state observer (ESO). The control variable can be obtained through subtracting the estimator of ESO from the output of NLSEF. The simulation results show that the controller operates robustly under modeling uncertainty and external disturbance and produces better dynamic performance than the ADRC controller.
