@@@@This paper is concerned with the problem of dynamic output feedback fuzzy control for networked systems subject to data dropout. The plant is a nonlinear system described by a T-S fuzzy model. A switching fuzzy controller is presented based on the data dropout status in the network and generalized parallel distributed compensation technique. The resulting closed-loop system is a switched system composed of two fuzzy subsystems. The stability analysis of the closed-loop system is first proposed by using a fuzzy Lyapunov function approach and an average dwell-time method. The switching fuzzy controller is then designed for the asymptotic stability of the networked control system. Finally, the applicability of the developed theoretical result is illustrated by networked control of a stirred tank reactor.
