Real-Time Failure Diagnosis Technology for Satellites Based on Multi-signal Model

In this study, the basic idea of multi-signal flow graph modeling method is summary analyzed, and the specific ways to build a multi-signal model is determined. The multi-signal model is built for typical subsystem of satellite. Then, the real-time fault diagnosis based on multi-signal is deeply studied. On the basis of analysis the capacity needs on real-time fault diagnosis for satellite systems, the algorithm of basic TEAMS-RT and distributed fault diagnosis is investigated.
