1) fault tree decomposition
故障树分解
1.
According to the structural characteristics of equipment,a redundant features approach is put forward based on fault tree decomposition.
特征参数是故障诊断的基础和关键,然而特征参数中总是存在很多冗余特征,影响故障诊断的准确率;根据设备的结构特点提出了基于故障树分解的冗余特征处理方法;首先,采用基于分类的粗糙集算法对不同部件的冗余特征进行约简,根据故障树结构分层处理;进而采用Apriori算法挖掘隶属于同一父节点的部件的频繁特征,降低不同部件特征参数的相关性;仿真实验证明,对原始特征进行冗余处理后,故障诊断系统的性能有较大提高。
