Robust adaptive finite-time fault-tolerant tracking control for uncertain systems
Robust adaptive finite-time fault-tolerant tracking control for uncertain systems
The adaptive finite-time fault-tolerant tracking issue of a class of uncertain systems is taken into consideration in this paper. The unknown time-varying actuator faults and uncertainties of both the system matrix and the input matrix are considered simultaneously when designing the control scheme. The unknown control parameters and gains caused by the actuator faults and model uncertainties are estimated by the designed adaptive laws to construct the fault-tolerant controller. Lyapunov stability analysis shows that the finite-time convergence property of the closed-loop system can be accomplished with great robustness to actuator faults and uncertainties guaranteed. Simulation results of an application to an aircraft model are illustrated to highlight the effectiveness of the proposed methodology.

Abstract
The adaptive finite-time fault-tolerant tracking issue of a class of uncertain systems is taken into consideration in this paper. The unknown time-varying actuator faults and uncertainties of both the system matrix and the input matrix are considered simultaneously when designing the control scheme. The unknown control parameters and gains caused by the actuator faults and model uncertainties are estimated by the designed adaptive laws to construct the fault-tolerant controller. Lyapunov stability analysis shows that the finite-time convergence property of the closed-loop system can be accomplished with great robustness to actuator faults and uncertainties guaranteed. Simulation results of an application to an aircraft model are illustrated to highlight the effectiveness of the proposed methodology.
