| Abstract: | It considers a fault diagnosis method of analytical redundancy relations based on the bond graph model. Diagnostic bond graph through adding virtual sensor in the bond graph of the system is set up, analytical redundancy relations and system failures characteristic matrix under the causal path of diagnostic bond graph model is built, and the observed characteristics and fault characteristics to do fault detection and isolation is compared. The simulation result through the two-tank system proves that the method is convenient and effective. |
