Abstract:

In the context of carrier-based joint operations， carrier aircraft landing is a critical and challenging task. This paper proposes a Backstepping‑based Direct Lift Controller （BSDLC） that enables the pilot to command the flight‑path angle directly during the glideslope phase， thereby reducing the operational complexity of carrier landings and improving touchdown accuracy. The proposed control architecture uses the flight‑path angle as a primary guidance command and implements three independent channels-for flaps， horizontal tail， and throttle-to decouple landing maneuvers and thus reduce pilot workload. An adaptive law is incorporated to iteratively estimate uncertain model parameters， thereby diminishing the controller’s dependence on precise parameter values. Furthermore， a direct lift dynamic decoupling module based on balanced pitch rate feedback is introduced to coordinate flap and horizontal tail deflections， improving the decoupling between flight‑path and attitude angles. To further bolster disturbance rejection， an Adaptive Super‑Twisting Extended State Observer （ASTESO） is employed to estimate and compensate for external disturbances. A series of simulation tests on a carrier‑based aircraft approach landing model demonstrate that the BSDLC can rapidly adjust the flight‑path angle， suppress wake‑vortex disturbances， and achieve high precision landings while exhibiting strong robustness.
