Discrete event systems: Modeling, observation, and control

S Lafortune - Annual Review of Control, Robotics, and …, 2019 - annualreviews.org
This article begins with an introduction to the modeling of discrete event systems, a class of
dynamical systems with discrete states and event-driven dynamics. It then focuses on logical …

Opacity of discrete event systems and its applications

F Lin - Automatica, 2011 - Elsevier
In this paper, we investigate opacity of discrete event systems. We define two types of
opacities: strong opacity and weak opacity. Given a general observation mapping, a …

A uniform approach for synthesizing property-enforcing supervisors for partially-observed discrete-event systems

X Yin, S Lafortune - IEEE Transactions on Automatic Control, 2015 - ieeexplore.ieee.org
The problem under consideration in this paper is that of enforcement by supervisory control
of a given property on a partially-observed discrete-event system. We present a general …

A general architecture for decentralized supervisory control of discrete-event systems

TS Yoo, S Lafortune - Discrete Event Dynamic Systems, 2002 - Springer
We consider a generalized form of the conventional decentralized control architecture for
discrete-event systems where the control actions of a set of supervisors can be “fused” using …

Verification and enforcement of strong infinite-and k-step opacity using state recognizers

Z Ma, X Yin, Z Li - Automatica, 2021 - Elsevier
In this paper, we study the verification and enforcement problems of strong infinite-step
opacity and k-step opacity for partially observed discrete-event systems modeled by finite …

Synthesis of maximally permissive supervisors for partially-observed discrete-event systems

X Yin, S Lafortune - IEEE Transactions on Automatic Control, 2015 - ieeexplore.ieee.org
We present new results on the synthesis of safe, non-blocking, and maximally permissive
supervisors for partially observed discrete event systems. We consider the case where the …

Active fault tolerant control of discrete event systems using online diagnostics

A Paoli, M Sartini, S Lafortune - Automatica, 2011 - Elsevier
The aim of this paper is to deal with the problem of fault tolerant control in the framework of
discrete event systems modeled as automata. A fault tolerant controller is a controller able to …

Current-state opacity enforcement in discrete event systems under incomparable observations

Y Tong, Z Li, C Seatzu, A Giua - Discrete Event Dynamic Systems, 2018 - Springer
In this paper we tackle the opacity enforcement problem in discrete event systems using
supervisory control theory. In particular, we consider the case where the intruder and the …

Dealing with sensor and actuator deception attacks in supervisory control

R Meira-Góes, H Marchand, S Lafortune - Automatica, 2023 - Elsevier
We consider feedback control systems where sensor readings and actuator commands may
be compromised by an attacker intending to damage the system. We study this problem at …

Relative observability of discrete-event systems and its supremal sublanguages

K Cai, R Zhang, WM Wonham - IEEE Transactions on …, 2014 - ieeexplore.ieee.org
We identify a new observability concept, called relative observability, in supervisory control
of discrete-event systems under partial observation. A fixed, ambient language is given …
