| Abstract: |
The aim of the project is to develop multi-level coordination control approach
for concurrent discrete-event systems with modular structure and to apply this
approach to decentralized supervisory control with communication. It will be based
on the single-level coordination control with one central coordinator that we have
recently developed, but which fails for most of large-scale systems due to central
coordinator being too complex. Two different approaches, top-down and bottom-up, will be
developed using multi-level hierarchy of groups of subsystems and their coordinators.
The results will be extended to partially observed systems and evaluated on large systems.
Finally, these efficient techniques for structured (modular) systems will be applied to
decentralized control without a structured plant to compute a controllable sublanguage
that is by construction coobservable with respect to enriched observations given by the
structure of the coordinators on different layers. |
