Stability of uncertain networked control systems with communication constraints

This paper investigates the robust stabilization problem for stochastic uncertain systems with random time delay, where a digital communication channel with limited data rates connects the sensors and controllers. A sufficient condition for stabilization of such stochastic uncertain systems with random channel propagation delay, is derived. It is shown that there exists a quantization and control scheme to stabilize the unstable plant if the data rate of the channel is greater than the lower bound to be proposed in our result. Simulation results show the validity of the proposed scheme.
