Fault diagnosis based on fuzzy inference graph
基于模糊推理图的故障诊断

A fuzzy fault diagnosis inference graph was built according to the architecture of the system modules. The minimization of fault diagnosis was realized by simplifying fuzzy inference graph and employing fuzzy operations. Based on feature criteria of observation positions, a diagnosis matrix was formed to carry out successive inference through cause-effect. As a result, a fuzzy diagnosis rank was obtained, which optimized the diagnosis detection.
