【摘要】 本文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,采用模糊推理来调节切换控制的幅度,实现了高精度的位置跟踪,提高了控制系统的鲁棒性。通过 MATLAB 仿真,结果表明该控制器有效地抑制了摩擦力矩的影响,使控制性能得到了极大的改善。更多还原

【Abstract】 In this paper,a fuzzy sliding mode variable structure controller is designed to compensate the friction in the flight simulator servo system.A conventional fuzzy control is combined with sliding mode control,and fuzzy inference is used to regulate the magnitude of switch control so that controller designed can realize the high accuracy position track and enhance the robustness of system.It is shown that this controller suppresses the friction influence and enables the control performance to have the enormous improvement effectively in simulation results by MATLAB.更多还原
