The fault diagnosis of aircraft power system based on D-S Evidence Theory

摘要：

　　Dempsters rule of combination is commonly used in the field of information fusion, Aiming at the problem of related fault of aircraft power system, D-S theory is used to fuse multiple fault alarm information to get the only fault type accurately.Mathematical model of aircrafi power system fault diagnosis, and method of fusion was established by analyzing the fault phenomena and fault causes ,for 270 V high-voltage DC power system.The accuracy of the D-S Theory data fusion is better than single sensor judged fault by simulating and testing.A example is given to show that this fusion method is feasible and rational.
