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.
