Stabilization design of networked control systems

The model of NCS(Networked Control Systems) with dynamic output feedback controllers is presented when the network-induced random time-varying delays are bounded and the upper bound of which is longer than one sampling period. Based on this, this paper discretizes the model of continuous-time systems and applies augmented state-space method to it, and then establishes a discrete-time jump system model governed by a finite state Markov process. Appling interior-point algorithm to design stabilizing controllers for the system, this paper proposed an approach to get the feasible initial solution. Theoretical analysis and simulation on a cart and inverted pendulum with random time delay show that the dynamic output feedback controllers can make the system stable.
