键合图可对系统中不同能域的守恒变换过程进行统一建模，其模型包含各部件的因果关系。基于键合图的故障诊断方法是一种基于模型的故障诊断方法，分为定，和定量2种方法。对这2种方法的原理、优缺点以及应用情况进行了分析，重点介绍了键合图在混合动态系统故障诊断中的应用，最后对其发展趋势进行了展望。

Bond graphs can be used to build universal models for energy conservation transitions between different energy domains,and the models built contain causality of all components.Bond graphs based fault diagnosis is a kind of fault diagnosis method based on model,consisting of qualitative and quantita-tive bond graphs based fault diagnosis.The principles,advantages and disadvantages and applications of qualitative and quantitative bond graphs based fault diagnosis are analyzed,and the applications of bond graphs on hybrid dynamic systems are stressed for introduction.Finally,the developmental trend of bond graphs based fault diagnosis is forecasted.
