This paper is concerned with the H∞ controller design of networked control systems with state delay and uncertainty. A model of the networked control systems is provided in consideration of the non-ideal network conditions. By introducing some free-weighing matrices, the robust H∞ stability conditions are obtained based on Lyapunov Krsasovskii functional 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.
