Variable structure guaranteed cost control for uncertain networked systems with time delay

A novel method for the stability of a class of uncertain networked control systems with state delay and communication delay has been presented. Based on the lyapunov stability theorem, a sliding manifold that can compensate delay has been designed by using LMI approach. Then a guaranteed cost control law is given to make the sliding manifold stable. Finally, a numerical example is given to demonstrates the application and effectiveness of the proposed variable structure controller design method.
