Fault diagnosis based on fuzzy integrated function
Lei Xiao-ben · Systems engineering and electronics · 2004
In fault diagnosis based on decision-level information fusion, sensor-based decision always has subjectivity and ambiquity. A new decision-level fusion method is put forward: After probability distribution of each sensor is decision is obtained, a fuzzy integrated function is used to fuse the information and diagnose the fault. In this way, the problems of how to decide the information confidence level and how to select fusion rule in multisensor information fusion can be solved.
