Networked Control System (NCS) can be regarded as a special type of control system in which sensors, controllers and actuators are connected to a closed loop. Media-sharing characteristics, time-delay, data packet dropout and data displacement are inevitable phenomena in such a control system, which can greatly degrade the control performance, and even make the control system unstable. Alleviating these effects has become one of the most attractive research hotspots in the last two decades. All the above three problems can be summarized as the time-delay issue. There are two kinds of...
