| Abstract_FL | In order to improve the control performance of permanent magnet synchronous motor(PMSM),such as the tracking accuracy of the speed and the current,a high-order sliding mode observer based on the deadbeat predictive control method for PMSM is proposed in this paper.The mathematical model of the interior permanent magnet synchronous motor is established considering the parameter uncertainties and external load as lumped disturbances.To improve the robustness and the tracking accuracy of the proposed control algorithm,two third-order super twisting sliding mode observers are constructed to estimate and attenuate the lumped disturbances in the speed and current loops,respectively.An improved sliding mode reaching law is employed in the speed loop to reduce the chattering and improve the convergence rate.Finally,the proposed method is validated on the interior PMSM experiment platform,and compared with the conventional deadbeat predictive current control and exponential reaching law sliding mode speed controller.The experimental results show the effectiveness and superiority of the proposed method. |
