Abstract
The problems of system analyses and modelling processes in physical environments included in cyber-physical systems for their control are considered. The developed models should be interpreted together with information technology and other cybernetics tools for interacting with physical environments and controlling processes in these environments. Physical environments and the systems organized in them can be physically natural, created by man, including heterogeneous. Modelling is carried out in various problem areas and is based on the laws of conservation and use of the apparatus of mathematical physics. Local conservation laws in different environments are represented by partial differential equations. Based on these laws, the methods of system analytics formulate the goals of cyber-physical systems and functioning criteria. The implementation of cyber-physical systems includes the development of information and communication subsystems in the form of the Internet of things and databases. Actual problems of modelling technogenic systems using examples of underground and offshore pipeline transport of energy carriers. The functions of the applied controlling current were obtained to maintain the protective potential in the considered application for the protection of pipelines from corrosion as a result of modelling. Values of control functions are obtained using numerical methods. The implementation of control by tools of cyber-physical systems provides not only reliable monitoring but also accurate, real-time monitoring of protection for the entire pipeline located in the ground, in water and border areas.
