Fault tolerant constrained control for switching discrete-time systems with delays

In this paper, fault tolerant control (FTC) problem for discrete-time switching systems with delay and constrained input is studied. Sufficient conditions of building an observer are obtained by using common Lyapunov function. These conditions are worked out using cone complementarity technique. The obtained results are applied on a numerical example showing fault detection, localization of fault and reconfiguration of the control to maintain asymptotic stability even in presence of a permanent sensor fault and constraints on the control.
