Contingencies-Based Reconfiguration of Holonic Control Devices

Abstract

In this paper, we propose a dynamic approach to programmable logic controller (PLC)

A Hybrid Simulation/Physical Environment for Benchmarking Real-Time Distributed Control Systems

“…In particular, we are currently implementing physical agents or "holons" (McFarlane and Bussman, 2000) on the TINI platform that will interact with the hybrid environment in order to provide intelligence at the physical device level. These physical agents will be implemented using IEC 61499 function blocks (IEC, 2000) as described in (Olsen et al, 2004). This will allow our work on manufacturing scheduling and control (Brennan and O, 2004) to be extended to include real-time aspects.…”

A Pattern-Based Approach to Distributed Control System Design

“…This is particularly relevant when investigating dynamic reconfiguration. Although it is possible to perform proof-of-concept tests of dynamic reconfiguration, this requires pre-loading all of the classes required for reconfiguration (i.e., a "contingencies" approach to reconfiguration is required) [12].…”
