摘　　要：针对飞行模拟转台位置伺服系统中存在的非线性摩擦环节,设计了一种补偿摩擦的模糊趋近律滑模变结构控制器.在常规的滑模变结构控制中引入模糊控制,利用模糊控制器来调整滑模控制的趋近律参数.Matlab仿真结果表明,该控制器优于常规指数趋近律变结构控制器,有效地抑制了摩擦力矩的影响,保证了系统的快速性和鲁棒性,实现了高精度的位置跟踪.A fuzzy reach law sliding mode variable structure controller is designed to compensate the friction in the flight simulator servo system. A fuzzy control is combined with the conventional sliding mode control, and fuzzy controller is used to adjust the parameters of reach law of sliding mode control. The results show that this controller is superior to conventional variable structure controller based on index reaching law,sup-presses the friction influence,ensures speediness and robustness of the control system,and realizes the high accuracy position track in simulation results by Matlab.
