On relative coobservability of discrete-event systems
2015 American Control Conference (ACC), 2013We study a new concept of relative coobservability in decentralized supervisory control of discrete-event systems under partial observation. This extends our previous work on relative observability from a centralized setup to a decentralized one. A fundamental concept in decentralized supervisory control is coobservability (and its several variations);

Discrete Events in Power Systems
Discrete Event Dynamic Systems, 1999The relevance of Discrete Event System theory (whether synthetic or analytic) to power system analysis and control is not clear. However, based on several characterizations of the domain of discrete systems set forth in the January 1989 Special Issue of the IEEE Proceedings, on ’’Dynamics of discrete event systems‘‘ (Ho, 1989), we attempt to delineate ...

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

Aggregation in Hierarchical Discrete-Event Systems
Discrete Event Dynamic Systems, 2003The authors elaborate on the hierarchical partition of automata-based discrete-event systems and provide algorithms which can be applied in practical applications. In the first part of the paper, they focus on the question of how to obtain a decomposition of a hierarchical system.

On Consistent Reduction in Discrete-Event Systems
2019 IEEE 15th International Conference on Automation Science and Engineering (CASE), 2019In this paper we develop a general framework, called “consistent reduction” for formalizing and solving a class of minimization/reduction problems in discrete-event systems. Given an arbitrary finite-state automaton and a binary relation on its state set, we propose a consistent reduction procedure that generates a reduced automaton, preserving certain

Active diagnosis of discrete event systems
Proceedings of the 36th IEEE Conference on Decision and Control, 1998Summary: The need for accurate and timely diagnosis of system failures and the advantages of automated diagnostic systems are well appreciated. However, diagnosability considerations are often not explicitly taken into account in the system design. In particular, design of the controller and that of the diagnostic subsystem are decoupled, and this may ...
