基于改进MRAS的永磁同步电机滑模速度控制设计
Design of improved MRAS based sliding mode speed control of permanent magnet synchronous motor
摘要
Abstract
In allusion to the diminished observation accuracy in traditional model reference adaptive system(MRAS)observers under external interference and operational variations,an improved MRAS observer is proposed.The performance of the observer is further improved by rederiving the adaptive law in the traditional MRAS,considering the parameter distribution theory and introducing the resistive adaptive law.In order to solve the problem that traditional PI speed controllers cannot meet the requirements of high-precision control,a new approach rate is proposed,and a corresponding sliding mode speed controller is designed to replace the traditional PI speed controller.The simulation results demonstrate that,in comparison with the conventional PI controllers and sliding-mode controllers,the improved sliding-mode velocity controller and MRAS observer can exhibit superior control and observation performance,showing high stability and robust resistance to load disturbances.关键词
