Abstract :
Feedback control systems wherein the control loops are closed through a real-time network are called networked control systems. Based on the controlled process that is linear time-invariant system, the network induced delay is viewed as time-varying parameter uncertainties. An existing condition of robust guaranteed cost control law for networked control system is presented by Lyapunov method and robust control theory. The design method of robust guaranteed cost state feedback controller for networked control system is proposed in terms of linear matrix inequalities. Finally the simulation based on the networked control unstable system is studied. The simulation results show the proposed controller is feasible and effective.
