Creation and development of cyber-physical systems under condition of uncertainty interaction of subsystems

Abstract

The tasks of creation and development of cyber-physical systems are considered. Cybernetic and physical subsystems can be presented in digital and analog form. The physical subsystem that simulates nature is presented in an analog form. Physical subsystems and processes, both natural, in particular, and technogenic, can behave like “things in themselves.” Therefore, the processes of synchronization of analog processes with cybernetics are often difficult to formalize or are not performed correctly enough. This applies to both obvious cases in problem areas of ecology, mining, energy, and in computers under conditions of inappropriate behavior of programs, ensuring the reliability of testing. This leads to the emergence of uncertainties accompanying the integration of subsystems and control in the system as a whole. The nature of analog-to-digital and digital-to-analog conversion in the known representation requires taking into account the features at the level of this class of systems. These problems are considered at the levels of deterministic, stochastic and uncertainty. The well-known models of monitoring, control of a physical subsystem cannot be directly used for control. The development of correct control actions is considered from the standpoint of transforming such models. These models for dynamical systems are represented by differential equations. It is necessary to develop input-output models for the subsequent synthesis of controls.
