Abstract :
This paper studied the stochastic control problem of networked control systems. An optimal control law with the minimum performance cost criteria is designed for networked control systems subject to random time delays in the communication networks. The state feedback and output feedback control laws for the networked control system in delta operator domain are designed by using a dynamic programming approach. The derived optimal LQG controller can be used as a delay-compensator for networked control system with long time delays. Finally a numerical example is shown to illustrate the validity and efficiency of the proposed controller
