The Theory and Architecture of Network Control System

Network Control System (NCS) is a synthetic application which combines control science, computer science and network technology. NCS technology is more and more applied in industry control system because of its simple structure, easy maintenance and high reliability. This article reviews the development history of the NCS, and introduces its current research statuses. Based on the basic theories and composition of Networked control systems, the structure design of NCS sub-system and further research on NCS technical algorithm have been discussed theoretically in this paper. This paper deals with the problem of observer and controller design for a class of networked control systems where the network connection only exists between the sensor and controller. Finally, the future developments of NCS are outlined.
