改进模糊滑模的永磁同步电机控制
Improved fuzzy sliding mode control of permanent magnet synchronous motor
摘要
Abstract
This paper aims to improve the performance of mining traction PMSM.The study involves analysing the advantages and disadvantages of the exponential approximation law in traditional PMSM con-trol;designing an adaptive exponential approximation law based on the state quantity of the PMSM itself in operation,and accordingly developing an improved sliding mode controller;furtherly optimizing this controller and obtaining the improved fuzzy sliding mode controller.The results show that when unloaded,both the improved fuzzy mode controller and the improved sliding mode controller can start with no over-shoot,and the time to reach the reference speed of the improved sliding mode controller is 0.12 s faster than that of the sliding mode controller,and the time to reach the reference speed of the improved fuzzy sliding mode controller is 0.01 s faster than that of the improved sliding mode controller.With the load increasing suddenly,the maximum error of the improved sliding mode controller is reduced by 0.17%compared with the sliding mode controller;and the maximum error of improved fuzzy mode controller is reduced by 2.53%compared with the improved sliding mode controller.It is proved that the improved fuzzy sliding mode controller can effectively improve the control accuracy and dynamic performance of the system.关键词
