摘　　要：针对导弹电液伺服机构的跟踪控制问题,设计了一种模糊滑模控制方案。将高层滑模函数作为模糊控制系统的一维输入,简化了一般模糊滑模控制系统结构,从而得到具有少量规则的模糊滑模的设计方案。仿真结果表明了该方案可以减小跟踪误差,增强系统的鲁棒性和削弱控制信号中的高频抖振。Aiming at the tracking control problem of missile electro-hydraulic servo mechanism,a design method of fuzzy sliding solitary input of the fuzzy co mode control is presented. The superior sliding mode function is taken as the ntrol system, so the structure of the general fuzzy sliding mode control system is simplified. Then a fuzzy sliding mode design method which has a small quantity of rules is obtained. Simulation results indicate that the control approach can decrease the tracking error, enhance the system＇ s robustness and attenuate the high frequency chattering in the control signal.
