Supervisory Control Synthesis of Discrete-Event Systems using Coordination Scheme

TLDR
In this article, a control synthesis problem for a generator with a global specification and with a combination of a coordinator and local controllers is formulated and solved, and conditions under which the result coincides with the supremal controllable sublanguage are stated.
Abstract
Supervisory control of distributed DES with a global specification and local supervisors is a difficult problem. For global specifications, the equivalent conditions for local control synthesis to equal global control synthesis may not be met. This paper formulates and solves a control synthesis problem for a generator with a global specification and with a combination of a coordinator and local controllers. Conditional controllability is proven to be an equivalent condition for the existence of such a coordinated controller. A procedure to compute the least restrictive solution within our coordination control architecture is provided and conditions under which the result coincides with the supremal controllable sublanguage are stated.

TL;DR: A polynomial-time algorithm for verification whether a language is conditionally decomposable with respect to given alphabets is presented and it is shown that conditional decomposability is a weaker condition than nonblockingness.

Supervisory control of a class of discrete event processes

TL;DR: In this paper, the control of a class of discrete event processes, i.e., processes that are discrete, asynchronous and possibly non-deterministic, is studied. And the existence problem for a supervisor is reduced to finding the largest controllable language contained in a given legal language, where the control process is described as the generator of a formal language, while the supervisor is constructed from the grammar of a specified target language that incorporates the desired closed-loop system behavior.

TL;DR: The main focus of this paper is the presentation of the automata and formal language model for DES introduced by Raniadge and Wonham in 1985, suitable for the examination of some important control theoretic issues, and provides a good basis for modular synthesis of controllers.

A General Architecture for Decentralized Supervisory Control of Discrete-Event Systems

TL;DR: It is shown that under this architecture, a larger class of languages can be achieved than before since a relaxed version of the notion of co-observability appears in the necessary and sufficient conditions for the existence of supervisors.
