| Abstract: | It is important that the spacecraft can do the thermal fault diagnosis automatically when in orbit.Combined with the rule-based reasoning and the case-based reasoning,the hybrid inference engine was produced.The information database comprises the historical experiments and the expert knowledge,and is described by the production rules.Then the expert system is realized by VB language,and does well in practice through the test. |
