Active anti-disturbance carrier landing control with integrated direct lift

To address the challenging issue of automatic carrier landing with disturbances, this paper presents an active anti-disturbance control with integrated direct lift scheme. This control scheme is comprised of three controllers: the attitude controller for maintaining angle of attack and eliminating lateral tracking error, the integrated direct lift controller for eliminating longitudinal tracking error and the auto-throttle controller for maintaining the velocity. To estimate and compensate for the external disturbances, the extended state observer is designed, along with the implementation of sliding mode and nonlinear dynamic inversion methods. The stability of the controllers is proved by the Lyapunov theorem. Based on this control scheme, a novel automatic carrier landing system is developed, consisting of the glide path subsystem, the guidance subsystem, the aircraft subsystem and the control subsystem. To validate the efficacy of the proposed method, numerical simulations are conducted. The comparative results demonstrate that the proposed method is capable of achieving precise and safe carrier landing with external disturbances. Furthermore, the Monte Carlo test results provide compelling evidence of the superiority of the proposed method.
