Delay-dependent adaptive reconfiguration control in the presence of input saturation and actuator faults

Abstract

In this paper, an active fault tolerant control strategy is developed for a class
\nof linear state-delayed systems with unknown actuator faults and input constraints. The
\ndesign is a combination between a direct adaptive control algorithm and multiple model
\nswitching, and the μ-modification is introduced in the model reference control architecture.
\nThe main features of the proposed control strategy are the reliability and simplicity in
\ntracking against actuator faults. By Lyapunov-Krasovskii theory, the stability of overall
\nsystem is guaranteed and the boundness of all signals is ensured. Numerical simulation
\nresults demonstrate the effectiveness of the proposed fault-tolerant control scheme.
