%X The stability of discrete-time linear system with two delays and application to network control system are discussed.A discrete-time linear system with state delay，when its signal of the state gets out from system to controller，there are two cases.The first one is that it has two channels，one is input into controller directly，the other is transmitted via network，time-delay caused by network transmission.The second one is that it has single-channel via network.Based on Lyapunov stability theory，a sufficient condition to guarantee the system with two delays stabilization is obtained.By introducing some new variables，the derived condition is formulated in terms of Linear Matrix Inequalities（LMIs） so that the controller for two cases is easily obtained.Finally，three examples are given to illustrate the developed results.
