摘　　要：以普加乔夫-眼镜蛇机动为代表的超机动飞行是飞行器机动能力的一项关键衡量指标,对于近距空战格斗中的摆脱敌方攻击和改变敌我态势具有重要实战意义。然而,超机动飞行过程中的大迎角、过失速往往导致机翼气动效率严重不足、外界扰动的剧烈增加和气动特性的迅速变化,对控制器的设计和试验带来诸多挑战,如何实现有限时间内的预定轨迹完全跟踪便成为控制器设计的主要目标。分析并总结了超机动飞行的特点和超机动飞行控制的难点;介绍了迭代学习控制的研究进展,并详细综述了应用于超机动飞行的迭代学习控制方法所面临的非重复不确定性、初始状态偏差、学习约束和无模型等实际问题及解决思路;展望了迭代学习控制在超机动飞行中的应用前景和研究方向。针对具有有限时间、大迎角、过失速特点的超机动飞行,从迭代学习控制的角度给出解决方案,并实现学习过程的安全、有效和鲁棒,为超机动飞行技术的发展提供理论依据和工程参考。Super-maneuver flight represented by Pugachev’s cobra maneuver,as a key measure of the maneuverability of aircraft,is practically significant for getting rid of the enemy’s attack and changing the battlefield situation in close-range air combat.However,the high angle of attack and post-stall in supermaneuver flight generally lead to the serious shortage of wing aerodynamic efficiency,the drastic increase of external disturbances,and the rapid change of aerodynamic characteristics.It brings great challenges to the design and test of the controller.Realizing the complete tracking of the predetermined trajectory in a finite duration becomes the main goal of controller design.The characteristics and control difficulties of supermaneuver flight are analyzed and summarized.The research progress of iterative learning control(ILC)is introduced.The practical problems and solutions of ILC applied to super-maneuver flight,such as nonrepetitive uncertainties,initial state errors,learning constraints,and model-free problems,are summarized in detail.The application prospect and research direction of ILC in super-maneuver flight are prospected.ILC solutions are presented for super-maneuver with limited duration,high angle of attack,and post-stall in the consideration of safety,effectiveness,and robustness.The provided ILC solutions may provide the theoretical basis and engineering reference for the development of super-maneuver flight.
