Abstract :
This paper presents a graphical method used for Fault Detection and Isolation (FDI) of hybrid dynamic systems. The developed method is based on the notion of Global Analytical Redundancy Relations (GARRs) from the hybrid bond graph model, which describes the system behavior at all of its operating modes. We use a hybrid tank system to illustrate the concept of the GARR.
