Abstract :
In this paper, a new adaptive fuzzy Fault Detection and Isolation (FDI) approach of non linear Bond Graph (BG) uncertain parameters systems is proposed. In this approach two methods are combined: adaptive thresholds based method and a fuzzy logic method. A simulation example of a real system is provided to show the efficiency of the proposed method in comparison to to adaptive thresholds based method.
