Distributed Fault Diagnosis Using Petri Net Reduced Models
J. Arámburo-Lizárraga, Ernesto López-Mellado, Antonio Ramírez‐Treviño · 2006
This paper is concerned with the distributed diagnosis of discrete event systems (DES) using reduced interpreted Petri nets (IPN) models. Two contributions are presented extending a previous work from the authors. First, the condition of event detectability is relaxed over parts of the model where the faults are not expected; thus the diagnoser handles a reduced model. Second, a method for splitting the global model into communicating modules is proposed; this leads to the design of a set of distributed diagnosers.
