Review of Typical Interference Suppression Measures for Industrial Control Systems

Abstract

Interference suppression is one of the core issues in the research of industrial control systems, and the research of interference suppression methods is an essential technology to ensure the reliable and stable operation of control systems. In this paper, from the conductive coupling, common impedance coupling, capacitive coupling, inductive coupling and electromagnetic field coupling, and other propagation paths to start, a comprehensive and systematic description and analysis of all types of interference suppression, including magnetic loop suppression, cable shielding, surge suppression and isolation of interference and other related methods and measures, the basic principle of suppression, the implementation of the method and the characteristics of the analysis and summary of the choice of interference suppression methods for industrial control systems. The basic suppression principles, implementation methods, and characteristics are analyzed and summarized to provide a reference for the selection of interference suppression methods for industrial control systems.
