Adaptive Finite-time Fault-tolerant Tracking Control of a Class of Perturbed Systems

This paper is concerned with the finite-time fault-tolerant tracking control problem of a class of perturbed systems with actuator faults and external disturbances. For the sake of eliminating the effects of actuator faults and disturbances within a finite-time, a compensation control strategy is developed based on adaptive technique. Through the Lyapunov function and adaptive strategies, some results are provided to indicate that the adaptive control strategies can guarantee asymptotic tracking of systems within finite-time in the presence of actuator faults and disturbances. Simulation results of an F-18 aircraft are given to verify the effectiveness of the proposed method.
