Fuzzy output feedback guaranteed cost control for a class of networked control systems with long time-delay

This paper deals with the problems on the guaranteed cost control for a class of uncertain networked control systems (NCSs) with long time-delay. Based on T-S fuzzy model, the NCS model with a random long time-delay is firstly transformed into a discrete-time system model with uncertain parameters. Then, a sufficient condition for the existence of fuzzy output feedback guaranteed cost control law and upper bound of cost function for the systems are given by using the linear matrix inequality method. Furthermore, the fuzzy output feedback guaranteed cost controller is obtained by solving the corresponding convex optimization problem. Finally, a numerical example is provided to demonstrate the validity of the proposed method.
