Supervisor Localization of Discrete-Event Systems with Infinite Behavior

Supervisor Localization of Discrete-Event Systems with Infinite Behavior

Recently we developed supervisor localization, a top-down approach to distributed control of discreteevent systems (DES) with finite behavior. Its essence is the allocation of monolithic (global) control action among the local control strategies of individual agents. In this report, we extend supervisor localization to study the distributed control of DES with infinite behavior. Specifically, w...

Supervisor Localization of Discrete-Event Systems under Partial Observation

Recently we developed supervisor localization, a top-down approach to distributed control of multiagent discrete-event systems. Its essence is the allocation of monolithic (global) control action among the local control strategies of individual agents. In this paper, we extend supervisor localization by considering partial observation, namely not all events are observable. Specifically, we use ...

Decentralized prognosis of fuzzy discrete-event systems

This paper gives a decentralized approach to the problem of failure prognosis in the framework of fuzzy discrete event systems (FDES). A notion of co-predictability is formalized for decentralized prognosis of FDESs, where several local agents with fuzzy observability rather than crisp observability are used in the prognosis task. An FDES is said to be co-predictable if each faulty event can be...

Hierarchical control of aircraft propulsion systems: Discrete event supervisor approach

This paper presents an application of the recently developed theory of language-measure-based discrete event supervisory (DES) control to aircraft propulsion systems. A two-layer hierarchical architecture is proposed to coordinate the operations of a twin-engine propulsion system. The two engines are individually controlled to achieve enhanced performance and reliability, as necessary for fulfi...
