Takai S., Yamamoto T.. Intersection-based architectures for decentralized diagnosis of discrete event systems. Automatica 183, 112576 (2026); https://doi.org/10.1016/j.automatica.2025.112576.
Abstract
In this paper, two intersection-based architectures, named the normal-state-estimator-intersection-based architecture (N-SEI architecture) and the failure-state-estimator-intersection-based architecture (F-SEI architecture), are examined for decentralized diagnosis of discrete event systems. For each of these architectures, the corresponding notion of codiagnosability is defined. These defined notions of codiagnosability are incomparable with inference diagnosability for the inference-based architecture. In addition, codiagnosability for the N-SEI architecture is weaker than the existing notion of intersection-based codiagnosability, while codiagnosability for the F-SEI architecture is incomparable with it. For each of the N-SEI and F-SEI architectures, a method for verifying the corresponding notion of codiagnosability is developed.
