Controller failures analysis for uncertain discrete time systems with state and input delay

This paper deals with the problem of reliable control against controller failure for a class of uncertain discrete time systems with both state and input delay. The considered system is modeled as uncertain discrete switched system with stable and unstable subsystem. Based on average dwell time method, the sufficient conditions of exponential stability for system are given in terms of linear matrix inequality (LMI). Simulation example shows the effectiveness of the proposed methodology.
