Guaranteed Cost Control of Networked Control Systems with Long Time Delay

Feedback control systems wherein the control loops are closed through a real-time network are called networked control systems. Based on the uncertainty parameters model of networked control systems with long time delay, the exist conditions of guaranteed cost control law for networked control system with long time delay is presented by Lyapunov method and robust control theory for the first time. The design method of guaranteed cost state feedback controller for networked control system with long time delay is proposed in terms of linear matrix inequalities. In the end the simulations based on the networked control unstable system is studied. The simulation results show the proposed controller is feasible and effective.
