| 摘 要： | 针对灰色关联度方法用于发动机故障诊断精度低的问题,结合云理论和关联度分析方法,提出了云关联度方法,利用＂云滴＂能够反映映射的模糊性和随机性与整体＂形状＂变化分布这一特性,克服数据挖掘的模糊性和随机性问题,采用综合隶属度方法能够充分对数据进行挖掘,最终计算出云关联度.为了实现航空发动机传感器、部件单一故障的实时识别和诊断...

| Abstract: | Considering low accuracy problem of fault diagnosis for aircraft engine by gray relational analysis,the method of cloud relational analysis was proposed by integrating the cloud theory and the relational analysis.The characteristics of cloud droplets reflect fuzziness and randomicity of the mapping,and solve the problem in data mining while representing the distribution change of the integral shape.The comprehensive subjection method could mine information fully,then the cloud relation can be calculated.In ... |
