Synthesis of covert actuator and sensor attackers

L Lin, R Su - Automatica, 2021 - Elsevier
In this work, we shall investigate the problem of covert attacker synthesis in the framework of
supervisory control of discrete-event systems. Intuitively, the covertness property says that …

Design of supervisors for partially observed discrete event systems using quiescent information

Y Hu, Z Ma, Z Li - IEEE Transactions on Automation Science …, 2023 - ieeexplore.ieee.org
In this paper, we study the nonblocking supervisor synthesis problem in partially observed
discrete event systems modeled by finite-state automata. We consider a particular type of …

Stabilization of probabilistic finite automata based on semi-tensor product of matrices

Z Zhang, Z Chen, X Han, Z Liu - Journal of the Franklin Institute, 2020 - Elsevier
Probabilistic finite automata (PFAs) can exhibit a stochastic behavior, and its stabilization is
the basic and important problem in the control theory. In this paper, the stabilization with a …

Networked supervisor synthesis against lossy channels with bounded network delays as non-networked synthesis

L Lin, Y Zhu, R Tai, S Ware, R Su - Automatica, 2022 - Elsevier
In this work, we study the problem of supervisory control of networked discrete event
systems. We consider lossy communication channels with bounded network delays, for both …

Synthesis of the supremal covert attacker against unknown supervisors by using observations

R Tai, L Lin, Y Zhu, R Su - IEEE Transactions on Automatic …, 2022 - ieeexplore.ieee.org
In this article, we consider the problem of synthesizing the supremal covert damage-
reachable attacker, in the setup where the model of the supervisor is unknown to the …

On decidability of existence of fortified supervisors against covert actuator attackers

R Tai, L Lin, R Su - IEEE Transactions on Automatic Control, 2023 - ieeexplore.ieee.org
This work investigates the existence of fortified supervisors against covert actuator attackers.
For a supervisor that is nonresilient against covert actuator attackers, a fortified supervisor …

Offline supervisory control synthesis: taxonomy and recent developments

W Fokkink, M Goorden - Discrete Event Dynamic Systems, 2024 - Springer
This paper surveys recent advances in supervisory control theory since its 30 th anniversary
in 2017. We performed a systematic literature search and selected 272 relevant papers, with …

Observation-assisted heuristic synthesis of covert attackers against unknown supervisors

L Lin, R Tai, Y Zhu, R Su - Discrete Event Dynamic Systems, 2022 - Springer
In this work, we address the problem of synthesis of covert attackers in the setup where the
model of the plant is available, but the model of the supervisor is unknown, to the adversary …

Supervisor obfuscation against covert actuator attackers

R Tai, L Lin, R Su - ar** intruder
R Tai, L Lin, Y Zhu, R Su - Automatica, 2023 - Elsevier
In this work, we investigate the problem of privacy-preserving supervisory control against an
external passive intruder via co-synthesis of a dynamic mask, an edit function, and a …
