Abstract

The concept of control over network is widely accepted and used in the world of automation, so the stability, safety, and robustness of the distributed and control systems are of key im¬portance for their proper per¬formance. Thus, it is essential to search for solutions of remote control prob-lems like variable time-delay, data-loss, equipment malfunctions, and unauthorized network infiltrations. This paper gives an H∞ robust control algo¬rithm, which stabilizes a ZigBee networked control system in the presence of random delays, network overload, and data package loss.
