This paper concerns the observer-based adaptive control problem of uncertain time-delay switched systems with stuck actuator faults.Under the case where the original controller cannot stabilize the faulty system,multiple adaptive controllers are designed and a suitable switching logic is incorporated to ensure the closed-loop system stability and state tracking.New delay-independent sufficient conditions for asymptotic stability are obtained in terms of linear matrix inequalities based on piecewise Lyapunov stability theory.On the other hand,adaptive laws for on-line updating of some of the controller parameters are also designed to compensate the effect of stuck failures.Finally,simulation results for reference [1] model show that the design is feasible and efficient.
