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
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
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
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 …
