Detectability of Discrete Event Systems
IEEE Transactions on Automatic Control, 2007In this note, we investigate the detectability problem in discrete event systems. We assume that we do not know initially which state the system is in. The problem is to determine the current and subsequent states of the system based on a sequence of observations.

The control of discrete event systems
Proceedings of the IEEE, 1989A discrete event system (DES) is a dynamic system that evolves in accordance with the abrupt occurrence, at possibly unknown irregular intervals, of physical events. Such systems arise in a variety of contexts ranging from computer operating systems to the control of complex multimode processes.

On the history of Discrete Event Systems
Annual Reviews in Control, 2018Abstract The purpose of this article is to provide a viewpoint of the development of the field of Discrete Event Systems (DES). Necessarily incomplete, because of the breath of topics and richness of research results, this paper is mainly presented from a System Theory-Automatic Control (AC) perspective. Written with a certain emphasis at the dawn of

Observability of discrete event systems
1986 25th IEEE Conference on Decision and Control, 1986Using a nondeterministic state model for a discrete event process the problem of determining the current state of the system from a sequence of past events and state observations is examined. Conditions under which it is possible to truck the state of the process with sufficient accuracy to implement a given feedback control are determined.

Diagnosis of Discrete-Event Systems
2003Model-based diagnosis of DESs encompasses many challenging aspects and it is of practical interest in many real contexts, therefore it has spurred research both in the Artificial Intelligence and Automatic Control communities. In this Chapter a comparative analysis of several approaches in the literature is hinted, by pointing out both similarities and

Relation to Discrete Event Systems
2013In the final chapter, the relationship between feedback control systems and finite state systems is described. The event-driven types of discrete systems are particularly important. There are many of those types of systems, e.g., manufacturing systems, industrial robots, and computer networks.

Discrete Event System Specification
2012In this chapter, the classic DEVS formalism from Zeigler et al. will be introduced. It will be discussed in depth, which properties of the DEVS MoC impedes its exploitation for a hardware / software co-design flow. Thus, the SynDEVS MoC will be introduced which thoroughly refines the DEVS MoC to allow synthesis of SynDEVS models.

On the control of discrete-event systems
2005In this paper we have provided an overview of one trend among others in the development of a control theory for discrete-event systems. In view of the relatively long history of prior approaches to discrete-event control design (notably discrete-event system simulation, and analysis via Petri nets, starting in the 1960s; and investigations via queueing
