Research on Global Clock Synchronization Mechanism in Software-Defined Control Architecture
文献摘要：
Adopt software-definition technology to decouple the functional components of the industrial con-trol system(ICS)in a service-oriented and distributed form is an important way for the industrial Internet of things to integrate information technology,communica-tion technology,and operation technology.Therefore,this paper presents the concept of software-defined control ar-chitecture and describes the time consistency require-ments under the paradigm shift of ICS architecture.By analyzing the physical clock and virtual clock mechanism models,the global clock synchronization space is logically divided into the physical and virtual clock synchroniza-tion domains,and a formal description of the global clock synchronization space is proposed.According to the fun-damental analysis of the clock state model,the physical clock linear filtering synchronization model is derived,and a distributed observation fusion filtering model is con-structed by considering the two observation modes of the virtual clock to realize the time synchronization of the global clock space by way of timestamp layer-by-layer transfer and fusion estimation.Finally,the simulation res-ults show that the proposed model can significantly im-prove the accuracy and stability of clock synchronization.
