This paper presents a landing fault-tolerant control system for carrier-based aircraft with faulty actuators. The system can effectively suppress the external disturbance during landing and the adverse effects caused by faulty actuators. First，an autoregressive model based on least squares is used to predict the deck motion to obtain the accurate landing point under wave disturbances. Second，a glide path guidance law is designed to generate the flight path angle. In addition，fast terminal integral sliding mode controllers based on disturbance observers are designed，and the controllers are connected in series with low-pass filters. Finally，the Lyapunov function is utilized to prove that the tracking error of the fault-tolerant control method is uniformly upper bounded. The proposed method is compared with the proportional-integral-differential（PID）controller by the numerical simulation，and the results verify the feasibility of the proposed algorithm.
