Robust Diagnosis of Switching Systems

This paper presents an approach for robust diagnosis of switching systems based on an extended version of the timed failure propagation graph model. The extended failure propagation graph model is a labeled graph used for the representation of failure conditions and their propagation modeled as causal relations with timing properties for a general class of systems with both timebased and event-driven dynamics such as hybrid and discrete event systems. We introduce the extended model and describe the structure and main components of the failure detection and isolation system based on the proposed model
