Project Distributed Supervisory Control of Large Plants - DISC (acronym)
The European Commission supports the project financially by the EU.ICT
program, Challenge ICT-2007.3.3 (Information and Communication Technologies
(ICT)).

Supervisory control is a formal approach for the control of discrete event
systems that aims to solve logical problems of safety, resource allocation,
liveness, and fault diagnosis that can be encountered in all systems with a high
degree of automation. It provides a conceptual framework for developing methods
and tools for system design.
An open issue is the application of this
methodology to those control problems that arise in networked embedded systems.
These distributed plants are composed by several local agents that take
concurrently decisions, based on information that may be local or received from
neighbouring agents; they require scalable and self-organising platforms for
advanced computing and control.
An important feature of this type of
processes is the possibility of studying them at an appropriate level of
abstraction where the resulting model is a purely discrete event one. The
evolution is guided by the occurrence of asynchronous events, as opposed to
other real-time models where the event occurrence is time-triggered.
We plan
to use several techniques to reduce the computational complexity that is one of
the major obstacles to the technology transfer of supervisory control
methodologies to distributed plants. These techniques are: modularity in the
modelling and control design phases; coordinating control; modular state
identification and modular fault detection based on the design of decentralized
observers
