| Abstract: | This paper introduces the Satellite Control system Real-time Diagnosis Ex-
pert System (SCRDES) used for testing of the satellite performance and monitoring of the
satellite flight status on-ground. The system designed for satellite attitude control system
sums up principle and structural knowledge on satellite and experienced knowledge of space
experts and adopts the mixed model about deep and heuristic knowledge; then with the concept
of eigenparameters and its attribution, expresses effectivelly the dynamic charicteristic of the
closed-loop system; finally achieves the on-line real time fault diagnosis using parellel struc-
ture for data processing and knowledge processing. SCRDES is a new probing into AI and ES
technique in the space field and the dynamic process field. |
