Abstract
Possible Conflicts (PCs) are those minimally redundant subsystems, computed offline, that can be used for consistency-based diagnosis of physical systems. In this work we characterize Possible Conflicts for hybrid systems diagnosis in the Hybrid Bond Graph modelling framework, introducing the notion of HBG-PCs. We provide a method to compute the complete set of HBG-PCs before causality is assigned in the model, removing a previous assumption that the system model should have a valid causal assumption when every switching junction was set to on. We call this new concept Structural HBG-PC. We illustrate these issues with an prototypical example and discuss our contributions against other proposals in the literature.
