Aiming at the degradation of control system performance caused by model prediction errors due to parameter perturbation and model mismatch during the operation of permanent magnet synchronous motor (PMSM), a deadbeat predictive control method based on the improved sliding mode disturbance observer is proposed. First, aiming at the inherent chattering problem in sliding mode control, an adaptive hybrid reaching law for boundary layer based on sign function is designed to achieve smooth crossing at zero point. Then, fuzzy adaptive reasoning rules are designed to adjust the boundary layer width in real time to reduce the steady-state error, taking into account the rapidity of approaching sliding mode surface and chattering suppression, and the stability of the controller is proved. Finally, the feedforward compensation of the prediction model is carried out by using deadbeat current predictive control and fuzzy adaptive sliding mode disturbance observer to improve the robustness of the parameters. The experimental results show that this method can effectively compensate the parameter disturbance when the motor model parameters are mismatched, and the steady-state error is small and the dynamic performance is good.
