Abstract:This paper studies the stability and L2-gain problem for a class of systems with input delay subject to controller failure. When the controller fails, zero-order hold is adopted. The paper addresses how long and how frequent the failure can be and still maintain the system exponentially stable and weighted L2-gain. We first utilize switched delay systems including unstable subsystems to describe the controller failure problem. Then, the concepts of controller average failure frequency and failure length rate are introduced. Next, based on a novel piecewise Lyapunov functional including the large-delay-integral terms (LDIT), sufficient conditions guaranteeing exponential stability and weighted L2-gain of the considered system are developed. ? 2010 AACC.
