A Survey on Synchronous Control Architectures for Data Transmission Delay in Networked Control Systems

Abstract

Networked Control Systems (NCS) are widely applied in industrial automation, remote control and other fields. However, data transmission delay has severely affected the stability and real-time performance of systems, becoming a core bottleneck restricting their development. This paper systematically reviews the synchronous control architectures and key technologies for data transmission delay. Firstly, it analyzes the generation mechanism, characteristics of data transmission delay in NCS and its impact on system stability. Secondly, it elaborates the design ideas of current mainstream synchronous control architectures from three aspects: synchronous architecture principle, controller coordination method and delay compensation scheme. Thirdly, it summarizes the typical simulation platforms and performance verification methods, and compares the control effects of different strategies. Finally, it concludes the limitations of existing research and prospects the future development direction in complex network environments. This paper aims to provide a systematic technical reference for the theoretical deepening and engineering application of NCS.
