Information fusion method in fault detection and diagnosis
Qin Zu Xu, Zhang Hong Yue · 2002
In order to improve the reliability of fault detection and diagnosis (FDD) for dynamic system, it is important to make full use of the information from system knowledge and system measurements. This paper presents a scheme of information fusion in FDD. In the proposed scheme, the local fusion adopts multiple FDD strategies aiming at one measurement of the system, then the results of these strategies are fused. The global fusion will fuse the results of every local fusion.>
