This paper is concerned with the network control problem for linear time delay systems. We employ a Networked Control Systems (NCSs) model, taking into consideration both the network-induced delay and the time delay in the plant. On the basis of the given model, a controller design method is proposed by using the delay-dependent approach. An appropriate Lyapunov functional candidate is utilized to lead to new criteria by combining the free-weighting matrix method. The feedback gain of a memoryless controller can be derived by solving a set of Linear Matrix Inequalities (LMIs). Moreover, the correlation between the network-induced delay and the time delay in the plant is investigated. A numerical example is given to illustrate the effectiveness of our method and the reciprocal influences between the network-induced delay and the delay in the plant.
