Abstract
In standard supervisory control of discrete-event systems, partial (incomplete) observations are given by deterministic functions such as natural projections, which erase unobservable events, or masks, which can represent indistinguishable events, where two or more different events yield the same observation. However, communication channels in modern technological systems are not always reliable and can be attacked by malicious external agents. In that case, the plant observations obtained by the supervisor may not be deterministic, e.g., due to delays and losses, or external attacks. This paper considers a unified supervisory control framework with set-valued (nondeterministic) observations and proposes a simplified version of nondeterministic observability, together with a generalized normality. It shows how the results of hierarchical control can be extended to the networked and cyber-attacked discrete-event systems at the same time.
期刊介绍:
Automatica is a leading archival publication in the field of systems and control. The field encompasses today a broad set of areas and topics, and is thriving not only within itself but also in terms of its impact on other fields, such as communications, computers, biology, energy and economics. Since its inception in 1963, Automatica has kept abreast with the evolution of the field over the years, and has emerged as a leading publication driving the trends in the field.
After being founded in 1963, Automatica became a journal of the International Federation of Automatic Control (IFAC) in 1969. It features a characteristic blend of theoretical and applied papers of archival, lasting value, reporting cutting edge research results by authors across the globe. It features articles in distinct categories, including regular, brief and survey papers, technical communiqués, correspondence items, as well as reviews on published books of interest to the readership. It occasionally publishes special issues on emerging new topics or established mature topics of interest to a broad audience.
Automatica solicits original high-quality contributions in all the categories listed above, and in all areas of systems and control interpreted in a broad sense and evolving constantly. They may be submitted directly to a subject editor or to the Editor-in-Chief if not sure about the subject area. Editorial procedures in place assure careful, fair, and prompt handling of all submitted articles. Accepted papers appear in the journal in the shortest time feasible given production time constraints.
