Modeling and design of Networked Control Systems based output feedback control

The model of NCS (Networked Control Systems) with output feedback controller is presented for the case when the network- induced random time-varying delays are bounded and the upper bound of which is longer than one sampling period. Thus we established a discrete-time jump system model with Markov delay. Based on this, this paper gives the optimization method to design stabilizing controllers. This paper generalizes previous results on delay-less output feedback control systems and state feedback systems with Markov time delay. Theoretical analysis and simulation on a two input two output system with Markov time delay show that the output feedback controller we proposed can make the system stable.
