ABSTRACT Recently we developed partial-observation supervisor localisation, a top-down approach to distributed control of discrete-event systems (DES) under partial observation. Its essence is the decomposition of the partial-observation monolithic supervisor into partial-observation local controllers for individual controllable events. In this paper, we extend the partial-observation supervisor localisation to large-scale DES, for which the monolithic supervisor may be incomputable. Specifically, we first employ an efficient heterarchical supervisor synthesis procedure to compute a heterarchical array of partial-observation decentralised supervisors and partial-observation coordinators. Then, we localise each of these supervisors/coordinators into partial-observation local controllers. This procedure suggests a systematic approach to the distributed control of large-scale DES under partial observation. The results are illustrated by a system of automatic guided vehicles serving a manufacturing workcell.

局部观测下大规模离散事件系统的监督者定位

摘要 最近，我们开发了部分观察监督者定位，这是一种在部分观察下对离散事件系统 (DES) 进行分布式控制的自上而下的方法。其本质是将局部观察单体监督器分解为局部观察局部控制器，用于单个可控事件。在本文中，我们将部分观察监督者本地化扩展到大规模 DES，对于这种单一监督者可能是不可计算的。具体来说，我们首先采用高效的分层监督者合成程序来计算部分观察分散监督者和部分观察协调者的分层数组。然后，我们将这些监督者/协调者中的每一个本地化为部分观察本地控制器。该程序提出了一种在局部观测下对大规模 DES 进行分布式控制的系统方法。结果由服务于制造工作单元的自动导引车系统说明。
