Networked Predictive Control Systems with Data Dropout

Abstract

In recent years, networked control and data fusion technology have become popular control problems which have been extensively studied under various assumptions and scenarios [197, 235. 98, 145, 91, 2, 206]. There has been a growing interest in the design of controllers based on the network systems such as traffic, communication, aviation and spaceflight [236]. Particularly, the rapid rising of Internet makes Internet based control systems accomplish remote monitoring and adjustment over a long distance. This makes the control systems benefit from the ways of retrieving data and reacting to plant fluctuations from anywhere around the world at any time [34, 179, 129, 127]. In NCSs, the plant, controller, sensor, actuator and reference command are connected through a network. As the structure of NCSs is different from that of traditional control systems, there exist various specific problems in NCSs, for example, network delay, loss of data packets, network security and safety [213].
