DEALING WITH THE EFFECTS OF RANDOM TIME DELAY AND DATA DROPOUTS IN NETWORKED CONTROL SYSTEMS THROUGH ROBUST CONTROL
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 importance for their proper performance. Thus, it is essential to search for solutions of remote control problems like variable time-delay, data-loss, equipment malfunctions, and unauthorized network infiltrations. This paper gives an H ∞ robust control algorithm, which stabilizes a ZigBee networked control system in the presence of random delays, network overload, and data package loss.
Key words: networked control systems; robust control; H ∞ -infinity control; data loss; random time delay; ZigBee
