Fault diagnosis for discrete events systems described by partially observed Petri nets

F Arichi, B Cherki, M Djemai, SM Djouadi - ISA transactions, 2022 - Elsevier
Fault diagnosis problem is discussed for discrete events systems described by partially
observed Petri nets. Our goal is to detect and identify faults that may have occurred in both …

Diagnostic based on estimation using linear programming for partially observable Petri nets with indistinguishable events

A Chouchane, P Declerck, A Khedher… - International Journal of …, 2020 - Taylor & Francis
In this paper, we design a diagnostic technique for a partially observed labelled Petri net

Matrix approach to I‐detectability of partially observed discrete event systems

W Dou, H Li, Y Li - Asian Journal of Control, 2022 - Wiley Online Library
I‐detectability is an important issue in partially observed discrete event systems (DESs). In
this paper, a Boolean semi‐tensor product (BSTP) approach is proposed to investigate the I …

A semi‐symbolic diagnoser for fault diagnosis of bounded labeled petri nets

A Boussif, M Ghazel, K Klai - Asian Journal of Control, 2021 - Wiley Online Library
In this paper, we present a diagnoser‐based approach to deal with fault diagnosis of
bounded labeled Petri nets. The approach consists in building a semi‐symbolic diagnoser to …
