Invariants of Noise in Cyber-Physical Systems Components

The article is devoted to the invariant of internal electrical noise of electronic devices, which are components of cyber-physical systems. Time series of noise signals show chaotic behavior. Invariants are based on the autocorrelation function of dynamic time series. Insignificant differences on the micro-level devices lead to changes in the dynamics of time series. It is shown that the form of the autocorrelation function is unchanged for each electronic device of the cyber-physical system.

LIMITS OF THERMOELECTRIC TEMPERATURE DIFFERENCE MEASUREMENT TOOLS WITH AUTOMATIC ADJUSTMENT

The accuracy of temperature difference meters depends on technological parameters of controlled processes. The meters of temperature difference can be constructed for operation in a wider temperature range. Their accuracy is determined by the non-identity of the sensors transformation functions.

CYBER-PHYSICAL SYSTEMS AND THEIR SOFTWARE

In connection with the enhanced development of cyber-physical systems, considerable attention in the world is given to various aspects of their formation and operation. So in 2014, NIST, USA has created a Cyber-Physical System (further CPS) Community Working Group to bring together a wide range of professionals at an open, public forum to help identify and shape the main characteristics of the CPS to guide the design and implementation of “intelligent” programs in various areas, including smart production, transportation, energy and healthcare.
