Fault diagnosis method based on multi-information fusion with weighted D-S evidence theory and its application
摘要
Abstract
Aiming at the difficulty in fault diagnosis caused by insufficiency of failure probability for the new product, a fault diagnosis method based on multi-information fusion with the weighted D-S evidence theory was proposed,which was used to deal with the problem of the lack of fault probability distribution model or the non-effective of the accurate mathematical analysis. In order to regulate confidence degree of the present fault diagnosis estimation by use of the past accuracy about the fault diagnosis,the weighted D-S evidence theory was applied. The modified fault diagnosis with the past fault diagnosis accuracy was fulfilled. The results of the fault diagnosis for the late model marine meteorological instrument show that the proposed method is feasible and efficacious while the fault probability and the knowledge are insufficient.关键词
