In this study, the direct lift control (DLC) method was introduced into the carrier landing control law. The tra-jectory and attitude decoupling capability of DLC can be used to better track the ideal glide path. However, the final landing process of the carrier-based aircraft was disturbed by the strong carrier air-wake. In order to suppress the air-wake turbulence and improve the robustness of the automatic carrier landing system based on direct lift control (DLC-ACLS), an innovative design of a DLC-ACLS based on nons in gular terminal sliding mode combined with linear active disturbance rejection control (NTSM-LADRC) is proposed. Firstly, a carrier-based aircraft landing model is derived. Secondly, the LADRC method con-troller is designed, and In order to improve response charac-teristics of the controller, the nonlinear error feedback control law is designed by combining the NTSMC, and the Lyapunov function is constructed to prove the stability of the closed-loop system. Finally, the NTSM-LADRC-based DLC-ACLS simulation of a carrier-based aircraft is constructed. The simulation results of tracking ideal glide slope show that the anti-disturbance, robustness and tracking accuracy of NTSM-LADRC are better than the traditional LADRC and proportional-integral-derivative (PID) control methods.
