For the networked control systems, in which the bounded time delays occur and the upper bound is longer than a sampling period, the modeling and the state feedback control are studied. By analyzing all the possibilities of the bounded time delays, a model of networked control systems is proposed, which can be used to deal with the problem of time varying control law. The stabilization of this system is transformed into the robust stabilization of a set of systems. The state feedback controller is given according to the Lyapunov method, which guarantees the stability of the closed-loop system. A simulation example illustrates the effectiveness of the proposed method.
