This paper considers the stabilization problem of networked control systems concerned both bounded channel uncertainty and arbitrary packet loss. Based on a previous approach which considers packet loss only, this paper proposes a new model to describe the NCS with both packet loss and channel uncertainty in an unified framework. The stability conditions of networked control systems are given by a common quadratic Lyapunov function approach. We give an approach to design the dynamic feedback controller via solving linear matrix inequalities (LMIs). Finally, a numerical example with simulations is given to show the effectiveness of the approach.
