Non-fragile control for a class of networked switched fuzzy time-delay systems

The stabilization problem of a class of networked switched fuzzy time-delay systems is investigated under the assumption that the controller gain to be designed has variations, single-packet transmission, and network-induced delay less than one sampling period. The design method of the non-fragile state-feedback controllers and the switched laws is proposed based on parallel distributed compensation method and the multiple Lyapunov functions technique, such that the networked uncertain switched fuzzy time-delay system is globally asymptotically stable. A sufficient condition for the existence of non-fragile state-feedback controllers is given in terms of matrix inequalities. Simulation results show the effectiveness of the design method.
