Method of Digital Counterpart Creation of Physical Processes at Productive Foresight Modeling of Cyber-Physical Systems

The authors propose to provide for the use of digital counterparts of physical processes in the electronic equipment of cyber-physical systems in their design for a long duration of active existence, for example, spacecraft in orbit or in a long flight. At the same time, it is proposed to create a database of big data in which synthesized digital counterparts are stored in the on-board computers of cyber-physical systems. They are designed to monitor sensor readings of electrical, thermal, mechanical and other physical processes of space equipment. The algorithm of functioning of the proposed structure of the cyber-physical system is constructed. The paper experimentally confirms the need to take into account the mutual influence of heterogeneous physical processes of the space cyber-physical system when creating digital counterparts for it.
