Distributed supervisory control of discrete-event systems with communication delay

Distributed Supervisory Control of Discrete-Event Systems with Communication Delay

This paper identifies a property of delay-robustness in distributed supervisory control of discrete-event systems (DES) with communication delays. In previous work a distributed supervisory control problem has been investigated on the assumption that inter-agent communications take place with negligible delay. From an applications viewpoint it is desirable to relax this constraint and identify ...

Partial Observation in Distributed Supervisory Control of Discrete-Event Systems

Distributed supervisory control is a method to synthesize local controllers in discrete-eventsystems with a systematic observation of the plant. Some works were reported on extending this methodby which local controllers are constructed so that observation properties are preserved from monolithic todistributed supervisory control, in an up-down approach. In this paper, we find circumstances in ...

Supervisory Control of Distributed Discrete-Event Systems

A distributed discrete-event system consists of an interconnection of two or more subsystems. Control of a distributed system demands a set of controllers each receiving the observation stream of a local subsystem and providing a subset of enabled events to that subsystem. Several control architectures are defined in this chapter: Distributed control, distributed control with communication, coo...

On Coparanormality in Distributed Supervisory Control of Discrete-Event Systems

Decomposition and localization of a supervisor both are reduction methods in distributed supervisory control of discrete-event systems.Decomposition is employed to reduce the number of events and localization is used to reduce the number of states of local controllers.In decomposition of a supervisor both observation and control scopes are restricted, whereas in localization only control author...
