Robust Design for Network-based Control System with Random Time Delay

Aimed at resolving the problem of the random time delay of the network-based control system (NCS), this paper gives a state feed-back controller in a concise form which is expressed as the problem of the feasibility of a certain linear matrix inequality system based on Lyapunov stability theory. For any time delay satisfying 0lesdlesdmacr, the system with the control u=Kx(t-d) is globally asymptotically stable. And the emulational results show a good effect of this controller
