The fault tolerant flight control problem is studied in this paper for the aircrafts with actuator fault, modeling uncertainties, safety and performance constraints. Firstly, a nonlinear dynamic model of the civil aircraft is established. Secondly an fault-tolerant adaptive control algorithm is designed to deal with the civil aircraft system with uncertainties and actuator faults. To improve the flight control system safety and tracking performance, barrier Lyapunov functions (BLF) are introduced and combined with the Lyapunov analysis for the aircraft under actuator faults. Finally, comparative simulation results verify that the proposed BLF-based control strategy is feasible and effective by a simplified analytical aircraft longitudinal model and the nonlinear longitudinal model of Boeing 747-100/200.
