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.
