DESIGNING CUSTOM COMPUTING PLATFORMS FOR CYBER-PHYSICAL SYSTEMS

Abstract

The article analyzes the problems of creating custom cyber-physical systems (CPS) and approaches to their design using computing platforms. The features and typical problems of the three main scenarios of creating a CPS are shown: 1) by applied specialists only; 2) by IT specialists only; 3) by applied and IT specialists jointly. The last scenario is considered in detail. The need for explicit allocation of interfaces for interaction between applied and IT specialists, explicit allocation of the CPS computing platform, as well as the need to create custom computing platforms is justified. Classification of computing platform interfaces by formalization and flexibility criteria is introduced. Extensions of the traditional CPS design route are proposed to take into account the proposed principles of using custom computing platforms. The concepts of applied architecture and the CPS computing system microarchitecture are introduced. For custom CPS computing platforms, it is shown which components should be posed as reusable artifacts. As an example of a custom computing platform usage in a CPS design, the problem of creating a robotic laboratory complex for automatic execution of experiments is considered. The interfaces of the computing platform, the logic of their allocation and their characteristics are shown.
