Position Sensorless Fuzzy Active Disturbance Rejection Control of PMSM Based on Model Predictive Control

In order to improve the static precision and anti-interference ability of the permanent magnet synchronous motor (PMSM) vector control system, a hybrid control method is given in this paper. Firstly, the model predictive controller (MPC) takes the place of PI controller to achieve higher static precision and rapid dynamic response of current. Secondly, the active disturbance rejection controller (ADRC) combined with fuzzy control is used in the speed loop in order to resolve the contradiction between response speed and overshoot. Thirdly, the slide model observer (SMO) is added to obtain the position and the speed signal. Finally, through the comparative simulation experiments in the MATLAB/Simulink platform, the superiority of this method is verified.
