Hybrid Architecture for Spacecraft Diagnosis and its Application

Aiming at guiding the design of fault diagnosis system for spacecraft from top-level, we proposes a new hybrid diagnosis framework in this paper. A variety of possible information is taken into account for better diagnostic ability. First of all, the brief introduction of BEAM architecture is given. The shortage of BEAM and some improvement strategies are analyzed. Then the new hybrid diagnosis framework for spacecraft is given in detail, including the types of knowledge and the modules involved. Finally, an example of how to use kinds of information to design the diagnosis system under the guidance of this framework is given.
