Abstract：Most of the accidents have occurred during the carrier landing phase, which are caused by poor longitudinal flight path control of aircraft, while the major factors leading to performance degradation are carrier motion, airwake disturbance and actuator faults. Aimed at these special circumstances, a fault-tolerant control methold is proposed to apply in the design of longitudinal carrier landing system. First, the airwake disturbance is inhibited by the sliding mode control method based on nonlinear dynamic inverse. Then the radial basis functions neural network is added and compensated the systematic faults which are caused by the actuator faults through its universal approximation ability of nonlinear term. So the fault tolerant method achieves that the aircraft tracks the desired flight path precisely, and is tested with different types of actuator faults. Finally, the simulation results show that the design of fault-tolerant longitudinal carrier landing system has strong robustness and fault tolerant ability. The system improves the control precision of aircraft landing trajectory.
