摘　　要：本文在分析基于图论的故障诊断基本模型的基础上,针对航空航天等领域中较多采用冗余设计的特点,研究提出了一种包含冗余关系的系统故障诊断图论建模方法,在此基础上进一步研究给出了利用多信息进行综合故障诊断的方法及算法设计,并结合实例给出了故障诊断的具体步骤。According to the systerm which includes redundance desighn, such as aviation and aerospace, the basic model of fault diagnosis based on graph theory is studied and then the new method of system fault diagnosis to found graph theory model is researched. On the base of this model, the compositive fault diagnosis method according to the multiple information is further developed and the algorithm is designed. Finally, the procedure of fault diagnosis is given by the example.
