DECENTRALIZED INFORMATION SYSTEMS IN INTELLIGENT MANUFACTURING MANAGEMENT TASKS

Abstract

The object of research: the process of distributed management of production processes in intelligent manufacturing. The subject of the study: a model of a decentralized system of technological process management in the production area of a modern plant, taking into account the concept of Industry 4.0. The purpose of the research: improvement of the management methods of intelligent production processes to ensure the execution of the technological process resistant to external influences and to ensure the specified indicators of product quality. The following research methods are used: methods of analysis and synthesis of decentralized production systems, modeling methods and theories of automatic control, mathematical apparatus of matrix theory, methods of describing linear dynamic systems. Obtained results and conclusions. In this work, the simulation of the decentralized information system for controlling the production site of intelligent manufacturing using manipulator robots with an angular coordinate system based on servo drives, which act as stepper motors, is carried out. To ensure the stability of the distributed system, parallel decentralization of the control process is proposed and the architecture of the organization of interaction between the components of the cyber-physical system based on it is given. A feature of the proposed model is the consideration of sensors as part of the feedback of the decentralized control system. The result of the simulation is the stability of the decentralized cyber-physical system to external influences for the selected transient characteristics.
