Guaranteed cost control for nonlinear networked control systems with long time-delay

This paper considers the guaranteed cost control problem for uncertain nonlinear networked control systems with long time-delay. Firstly, the networked control system model with random long time-delay is transformed into a discrete-time system model with uncertain parameters. Then, the Lyapunov stability theory and the LMI approach are applied to design a guaranteed cost control law, which results in the closed-loop system is asymptotically stable and the system´s performance index less than a determinate super bound. At the same time, the existence conditions and the design approach of guaranteed cost control law are presented. Finally, simulation results show that the method is effective.
