Codiagnosability for Intersection-Based Decentralized Diagnosis of Discrete Event Systems
Shigemasa Takai, Takashi Yamamoto · IFAC-PapersOnLine · 2023
In this paper, we examine 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), for decentralized diagnosis of discrete event systems. For each of these architectures, the corresponding notion of codiag-nosability is defined. The defined notions of codiagnosability are incomparable with inference diagnosability for the inference-based architecture. Besides, codiagnosability for the N-SEI architecture is weaker than the existing notion of intersection-based codiagnosability.
