Bond Graph model-based fault estimation in presence of uncertainties: Application to mechatronic system

Abstract

This paper deals with the fault estimation problem of uncertain systems using Bond graph model-based technique.The main objective is to enhance the fault estimation procedure based on the generation of the fault estimation thresh-old, in order to overcome the problem related to errors in the estimated fault. 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.
