The novelty of the proposed method is the generation of the fault estimation error us-ing the fault estimation equation, which can be generated from the Bond graph model. The proposed methodology is validated via simulationsof a mechatronic system.enBond graph model-basedFault detection and isolationFault detection and isolationUncertaintiesMechatronic systemArticle
