基于信息融合的控制系统故障诊断

Information fusion and its application in controling system fault diagnosis

介绍了多传感器数据融合的基本概念、主要优点、结构以及它的方法和应用 ;对故障诊断进行了简要叙述 ,介绍了故障诊断信息融合过程 ;分析了多传感器数据融合和故障诊断的特点以及适合于控制系统故障诊断的信息融合的层次结构 。

The basic concept, main advantage, architecture, method and application of multi\|sensor data fusion are described. Data fusion is the process of combining, correlating, and associating data from multi\|sensor or other information sources to identity estimation and assessment of situations. Some general problems on fault diagnosis are introduced. The process of data fusion of fault diagnosis are also introduced. Their specialty and the layered fusion architecture fitting with fault diagnosis of control system are analyzed, and an architecture of fault diagnosis which is based on the information fusion are deeply investigated.
