摘　　要：研究了一种利用位置信号误差和滑模增益之间的非线性关系来设计的滑模增益,再结合变指数趋近律来改善滑模控制的鲁棒性及削弱滑模抖振,并将这种新的变指数趋近律滑模变结构应用于永磁同步电动机伺服系统的位置控制。应用Matlab/Simulink及Matlab编程建立了永磁同步电动机伺服系统的矢量控制系统的仿真模型,仿真结果表明,该滑模控制方法不仅有效抑制了滑模变结构的抖振,还增强了控制系统的鲁棒性。This paper studied the non-linear relationship among the position signal error and sliding gain to design the sliding mode variable gain and combined the exponential rate reaching law to improve the robustness of the sliding mode control and weaken the sliding mode chattering,and the new exponential rate reaching law sliding mode variable structure was used in permanent magnet synchronous motor position servo system control.The application of Matlab/Simulink and Matlab established permanent magnet synchronous motor servo system of vector control system simulation model.The simulation results show that this method not only can effectively restrain sliding mode control the sliding mode variable structure buffeting,while improving the robustness of the control system.
