The H-infinity cost-guaranteed control problem is considered for a class of uncertain nonlinear networked control systems(NCSs)with long time-delay.Firstly,the NCS model with a random long time-delay is transformed into a discrete-time system model with uncertain parameters;and then,the Lyapunov stability theory and the linear matrix inequality(LMI)approach are employed to develop the existence condition and to design the H-infinity cost-guaranteed controller.Furthermore,the optimal robust H-infinity cost-guaranteed controller is obtained by solving the corresponding convex optimization problem.Finally,simulation results show the validity of the proposed control algorithm.
