针对卫星故障诊断中应用同一征兆域信息难以区分的故障,提出了一种基于证据推理理论的故障诊断新方法。该方法应用证据推理理论实现卫星故障不同征兆域信息的融合,从而获得更加准确的故障定位。文中分析了卫星故障诊断中应用证据推理理论进行信息融合的必要性,研究了应用证据推理理论实现卫星故障不同征兆域信息融合的理论方法,给出了该方法的实际应用,讨论了应用该方法需注意的问题,最后给出了结论。
Aiming at the fault that the same symptom domain information is indistinguishable in satellite fault diagnosis, a new fault diagnosis method based on evidence reasoning theory is proposed. The method uses the theory of evidence reasoning to achieve the fusion of different symptom domains of satellite faults so as to obtain a more accurate fault location. In this paper, the necessity of information fusion based on evidence reasoning theory in satellite fault diagnosis is analyzed. The theoretical method of information fusion in different symptom domains of satellite fault using evidence reasoning theory is studied. The practical application of this method is given. The application of this method Attention should be paid to the conclusion.
