All the possible fault types of multi-tank system are introduced
and the structure and characteristics of multi-tank system are analyzed.The sensor fault of multi-tank system is researched through new type of method of analytical redundancy relationship( ARR) based on bond graph model.Firstly
the multi-tank system bond graph model is proposed by he theory of bond graph.Diagnostic bond graph through adding virtual sensor in the bond graph of the system is set up
and obtain ARR.To build the system fault feature matrix by analyzing the causal relation of diagnostic bond graph model.Finally
all kinds of fault are analyzed by simulation with 20-sim bond graph simulation software
and feasibility of the new type of method of ARR based on bond graph model in sensor fault detection and isolation is verified.
