Stabilization of Networked Control Systems with Time Delay

This paper investigates the stabilization problem for networked control systems, where sensors, controllers and plants are connected by a digital communication network. A sufficient condition for stabilization of linear time-invariant systems is derived. An upper bound on the maximum allowable transfer interval, below which there exists a feedback control policy to stabilize the unstable plant, is proposed. Simulation results show the validity of the proposed control scheme.
