| 摘 要： | 对Bandekar提出的一种因果故障诊断方法,在因果关系图的基础上利用模糊阈值及模糊评判矩阵,提出了一种能够利用故障概率,对故障源候选集进行排序的方法。该方法有利于故障定位,可提高故障诊断速度,同时还使诊断结果对噪声及参数选择具有鲁棒性。

| Abstract: | To one kind of causal diagnosis method represented by Bandekar, based on the causal graph, by utilization of fuzzified threshold and fuzzy discrimination matrix, a new method of finding the root fault according to the fault possibility is brought forward. This method is favour of the fault location, and can raise fault diagnosis speed. The result is more robust to noises and bad parameter's choice. |
