Abstract
AbstractPermanent magnet synchronous motors (PMSM) have been extensively adopted due to their perfect dynamic properties and compact structure. Reliable controller of PMSM requires high speed-following capability and anti-disturbance ability when the parameters of the system change suddenly. Therefore, it is important to improve the performance of speed and torque control of PMSM. In this article, a novel model predictive control method is presented to track the speed of PMSM by using a sliding mode model. Firstly, a drive model of PMSM and sliding mode predictive model have been built for controller design. Then the control variable is designed by combining sliding mode control and model predictive control. Finally, the simulation results are presented to evaluate the validity of the proposed algorithm. Furthermore, the comparison between the proposed controller and the controller using traditional model predictive control implies the quickness of speed response and the robustness of the sliding mode predictive controller.KeywordsPermanent magnet synchronous motorModel predictive controlSliding mode control
