摘要

The main goal of the paper is to develop two new causal graph-based fault detection and isolation algorithms. Easily calculated from the Hyper-graph (respectively Directed Hyper-graph) representation covering the hyper-paths, the qualitative residual generators are systematically deduced. The number of redundant relations can be reduced as information is added by a qualitative indicator for each term in the signature vector. Compared with the well-known classical bond graphs, structural fault monitoring ability is improved without additional computational costs. The proposed frameworks are illustrated through a pedagogical example.
