A Fault Diagnosis Method for In-Orbit Satellite Based on Credibility and Degree of Membership

Article Preview

Abstract:

The mistake rate of in-orbit satellite diagnosis reasoning is a problem which is difficult to solve because of the complex technique frame of satellite and the bit errors of telemetry data. This paper proposed a diagnosis reasoning method based on credibility and degree of membership. And the credibility passing algorithm and the membership function prototype were given to support the diagnosis reasoning process. The argumentation indicates that the diagnosis reasoning mistake rate can be reduced with this method.
