Multi-Agent Modeling of Cyber-Physical Systems for IEC 61499 Based Distributed Automation

摘要

The traditional industrial automation systems developed under IEC 61131-3 in centralized control are statically programmed with determined procedures to perform predefined behaviors/tasks in structured environments. A major challenge for the traditional system is the frequent changes and constant uncertainties of the system itself, its operations and the operating environments. Therefore, in this paper we are trying to develop a two-layer architecture for modelling industrial cyber-physical systems, in which the multi-agent computing model is designed for the high-level architecture and the IEC 61499 function block model is applied for the low-level architecture. It aims to integrate system intelligence by communicating and computing cores from the high-level cyber modules and real-time adaptation by distributed and intelligent control of the low-level physical modules. The proposed modeling framework is tested for the feasibility study through preliminary experiments on Jetson Nano and Raspberry Pi by using agent modeling tool SPADE and function block modeling tool Eclipse 4diac.
