摘要：

A novel speed control method based on nonlinear predictive control and sliding mode disturbance observer is proposed for permanent magnet synchronous motor (PMSM). Firstly, the nonlinear predictive control method is introduced to the speed control system of PMSM. Through optimizing the cost function, the speed controller is designed. Then, in order to decrease the influence of the disturbance, such as the load disturbance and the parameter variations, a sliding mode disturbance observer is designed to estimate the lump disturbance, which is used to the feed-forward compensation control. The robustness is improved effectively. Lastly, the effectiveness of the proposed control method is verified through simulation and experiment. The results show that the designed controller has good tracking performance and strong robustness for the disturbance. © 2017 Editorial Department of Journal of Beijing Institute of Technology.
