Supervisory Control of Product and Hierarchical Discrete Event Systems

Supervisory Control of Product and Hierarchical Discrete Event Systems

In this paper, the supervisory control of a class of Discrete Event Systems is investigated. Discrete event systems are modeled either by a collection of Finite State Machines that behave asynchronously or by a Hierarchical Finite State Machine. The basic problem of interest is to ensure the invariance of a set of particular configurations in the system. When the system is modeled as asynchrono...

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 ...

Discrete Event Systems Modelling and Supervisory Control

Discrete-event models are generally used to describe systems where coordination and control is required to ensure the orderly flow of events, or to avoid the occurrence of certain chains of events. Reduced Supervision and Hierarchical Supervision are methods of obtaining a supervisor in which control is divided or we can say that the control is distributed. In this paper the Problem of Guide Wa...

Supervisory Control Of Discrete Event Systems

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...
