Abstract

A problem of task rescheduling using a coordinator in a structural decentralised control of discrete-event systems is formulated. After the local supervisors have been designed for a given task, a coordinator can be used to solve some rescheduling problems among local plants. The coordination system models the interactions of local plants, and is consisting of only the shared events, so simpler to synthesise. Under the conditions developed in this paper, the combined concurrent actions of the coordinator with the existing local supervisors can achieve the rescheduling requirements. An example is provided for illustration.

离散事件系统结构分散控制中使用协调器的任务重调度
提出了离散事件系统结构分散控制中使用协调器的任务重调度问题。在为给定的任务设计了本地监督器之后,可以使用协调器来解决本地工厂之间的一些重新调度问题。协调系统模拟了当地植物之间的相互作用,并且仅由共享事件组成,因此更容易合成。在本文提出的条件下,协调器与现有的局部监督器的联合并发动作可以实现重调度要求。提供了一个示例来说明。
