基于多Agent的卫星故障诊断融合技术研究

为提高基于多Agent的卫星故障诊断系统的诊断准确性，充分利用已有的各种诊断方法获取的诊断信息，在分析故障诊断原理的基础上，提出了将数据融合技术应用于多诊断Agent的思想；并根据卫星故障诊断的特点，将权重引入多诊断Agent的诊断结果融合技术中，给出了权重的具体确定方法和改进的D—S证据理论，最后举例验证了该方法的有效性。

Research of Multi-Agent Based Satellite Fault Diagnosis and Fusion Technology

In order to improve the accuracy of Multi Agent based fault diagnosis system for satellite and to make use of diagnosis information captured by every diagnosis method, technology of data fusion is introduced into Multi Agent diagnosis based on the analysis of fault diagnosis theory . Weights are introduced into fusion of diagnosis result according to the feature of satellite fault diagnosis. The improved Dempster Shafer evidential theory arithmetic and the method of weights calculating are given. At last, validity of the method is proved by an example given in this paper.
