摘要
Abstract
In order to increase the precision and accuracy of analog circuit fault diagnosis ,the paper uses information fusion method for fault diagnosis .First ,take the output gain under different frequency as characteristic parameters ,three meth-ods ,including ANFIS model ,BP model and RBF model ,are considered as primary diagnosis ,which can obtain independ-ent evidence .Then use the method of D-S evidence theory evidence to decide the fusion fault location ,and join the local di-agnostic accuracy of the acquisition of basic probability assignment .Through its application in a circuit ,it indicates that by multi-level information fusion treatment ,not only significantly increase the credibility of diagnostic conclusions ,but also improve the diagnostic accuracy .关键词
