Abstract: A delayed state-variable model for networked control systems was presented. Considering the model uncertainty and external disturbance, a sufficient condition on the existing of robust controller was proved. A method of designing and optimizing the controller was also given. Simulation results prove that the novel controller can robustly preserve the performance in terms of network delays and model uncertainty.

Key words: control, network, networked control systems, delays, robust
