摘　　要：舰尾气流扰动是影响舰载机着舰误差的主要因素之一,为提高着舰精度,消除舰尾气流扰动对着舰安全的影响,提出了运用模糊-滑模控制抑制舰尾气流的扰动。滑模控制系统在滑动模态时对系统的不确定性及外界干扰具有很强的鲁棒性,运用模糊控制理论建立了随系统状态变化的时变滑模面,所设计的模糊-滑模控制系统可以较早达到滑动模态,并最后进入预定滑模面,使其同时具有良好的动态特性和抗干扰能力。纵向自动着舰导引系统的仿真实例验证了其有效性。The carrier air wake disturbance is one of the major factors that cause carrier plane touchdown error.Fuzzy-sliding mode control is presented to eliminate air disturbance.The sliding mode control system has strong robustness against system uncertainties and external distur- bances.The time-varying sliding surface is built using fuzzy logical theory.The designed sliding mode control system can immediately run in the sliding mode by minimizing the reaching phase,and run on the sliding surface of the special character finally.So the system has the good dynamical performance and the good capability of the rejective disturbance.As an example the longitudinal automatic carrier landing system is simulated.And it is proved feasible.
