摘　　要：为了提高系统扰动较大时永磁同步电动机伺服系统位置跟踪响应的快速性和精确性,在普通滑模控制策略中引入自适应模糊控制算法,设计了基于自适应律的模糊滑模切换控制器。通过Lyapunov稳定性分析设计参数自适应律,同时也证明了控制系统的稳定性。通过理论分析、MATLAB/Simulink纯仿真实验以及基于AD5435的半实物仿真实验,验证了该算法在系统扰动较大时不仅能保证系统鲁棒性,而且能有效抑制系统抖振,使永磁同步电动机伺服系统获得准确的位置响应。In order to improve the speed and accuracy of the position tracking response of permanent magnet synchro- nous motor servo system when the system was disturbed, a fuzzy sliding mode controller based on adaptive law was designed by combining switching fuzzifieation adaptive control algorithm with traditional sliding mode control method. Through Lya- punov stability analysis, parameter adaptive laws was designed and the stability of servo system based on switching fuzzy a- daptive sliding mode control algorithm was proved. When the system is disturbed, theoretical analysis, MATLAB/Simulink pure simulation experiment and the semiphysical simulation experiment based on AD5435 results show this algorithm can re- duce chattering, has strong robustness and make PMSM servo system obtain accurate position response.
