摘要 首先建立起BGM模型的方程定义形式,并在此基础上设计出了求BGM模型全体相容故障模式的方程诊断算法.该诊断算法在实施系统级故障诊断时与以往算法相比没有“t-可诊断性”和“相信大多数”的诊断前提,因而较好地解决了以往诊断算法的适用范围问题. In this paper,the definition of BGM fault model by using equations model is given firstly,then the equation diagnosis algorithm of finding all consistent fault patterns about BGM model based on it is proposed.Comparing to previous diagnosis algorithm,the proposed algorithm has no hypothesis of 't-diagnosable' and 'believe the most' while finding the diagnosis result.So it provides a good solution about the application range of previous diagnosis algorithm.
