Abstract(s)
A general concern in industrial world is related to process maintenance, safety and availability problems in the presence of faults. Most industrial processes are very large or/and complex. Because of size and complexity, it is very difficult to make a diagnostic system for an entire process and to ensure the availability of it. Designing a Fault Tolerant Networked Control System (FTNCS) to deal with large-scale complex networked control systems is a very difficult task due to the large number of sensors and actuators spatially distributed and networked connected. This paper presents a toolkit to implement multiagent approaches on distributed FTNCS. The design methodology is made easier using the toolkit presented in this paper. The FTNCS design method is able to use simple and verifiable principles coming mainly from a decentralized design, based on causal modelling partitioning of the NCS and distributed computing using multi-agents systems, allowing the use of well established fault tolerant control methodologies, or new ones, developed taking into account the NCS specificities. A platform with a real process and four computers is used to test the toolkit and network infrastructure.
