Robust Adaptive Control for a Class of Uncertain Switched Delay Systems with Actuator Failures

The problem of the reliable control for a class of uncertain switched delay systems containing actuator failures is addressed in this paper. The upper bounds of uncertainties are assumed to be unknown. When actuators suffer "serious failure"-the never failed actuators can not stabilize the given system, based on multiple-Lyapunov function method, the adaptive feedback controllers being able to estimate the upper bounds of uncertainties are derived in terms of linear matrix inequalities (LMIs) such that the resulting closed-loop system is uniform ultimate boundedness.
