摘　　要：战机在战场追逃过程中需要完成超机动动作以快速进入优势攻击区域,但在大攻角飞行范围内,飞行过程具有强烈的耦合作用。传统的动态逆控制方法具有很好的快速解耦能力,但鲁棒性较差。提出一种基于非线性动态逆的L1自适应飞行控制方法,通过引入PI型动态逆控制和L1自适应结构,提高了系统的动态性能和鲁棒性。最后利用某软件仿真战机类眼镜蛇机动,结果表明该方法在提升了系统动态性能的基础上,还可以有效补偿参数不确定性等扰动,同时提高了鲁棒性,能够为战机空中作战提供技术参考。During the pursuit and evasion process on the battlefield,the fighter aircraft needs to complete super-maneuver actions to quickly enter the dominant attack area.However,in the range of large angle-of-attack flight,the flight process is strongly coupled.Traditional dynamic inversion methods have good fast decoupling capability,but the robustness is poor.An L1 adaptive flight control method based on nonlinear dynamic inversion is proposed,which improves the dynamic performance and robustness of the system by introducing PI-type dynamic inversion control and L1 adaptive structure.Finally,a certain software is used to simulate the cobra maneuver of the fighter aircraft,and the results show that besides improving the dynamic performance of the system,the method can effectively compensate for such perturbations as parameter uncertainty and improve the robustness,which provides a technical reference for air combat of the fighter aircraft.
