Network-based Robust H_∞ Control of Systems with State-delay and Uncertainty

This paper is concerned with the H_∞controller design of networked control systems with state delay and uncer- tainty.A model of the networked control systems is provided in consideration of the non-ideal network conditions.By in- troducing some free-weighing matrices,the robust H_∞stability conditions are obtained based on Lyapunov Krsasovskii func- tional method,and an H_∞controller design method with time delay state feedback is also proposed.An illustrative example is provided to show the effectiveness of our proposed method.
