Delay characteristics and synchronization architecture of networked control system

Along with the extensive applications of computers and networks in the field of industrial control, the switched Ethernet and TCP/IP are increasing to be an important research domain. However, how to preserve the favorable stability and performance is getting more and more important when the error of time synchronization is caused by the nondeterministic network-induced delay in the networked control system. According to the analysis to the architecture of the networked control system based on the switched Ethernet, the time delay characteristics of it are presented in detail. And then the time synchronization architecture of networked control system confirmed by the simulation results is proposed.
