The defining characteristic of a networked control system (NCS) is having a feedback loop that passes through a computer network. Contrasting to this time delay introduced by the network, a delay-dependent stabilization condition of discrete-time linear system with time-varying delays is proposed. Based on this condition, the stabilization controller and H∞ controller of NCS are constructed and the solutions of these controllers are given through an iterative procedure of a linear matrix inequality (LMI) minimum problem which is derived from cone complementarity linearization algorithm. A numerical example is given to illustrate the proposed results.
