摘要
针对某飞行器地面电源故障诊断中的特点和难点,运用D-S证据理论对其电气故障智能诊断中的应用进行探讨。本文首先介绍D-S证据方法的基本理论,然后以某飞行器地面电源中的电气故障为例建立故障特征库,最后利用D-S证据理论对该飞行器地面电源故障融合的结构、算法等进行了仿真研究,取得了满意的效果。
According to the characteristics and the difficulties of some aircraft ground power fault diagno- sis, the application of electrical fault intelligent diagnosis based on D-S evidence theory is discussed. Firstly, the basic theory of D-S evidence method is introduced, and then by taking a aircraft ground power electrical failure as case study, the fault feature library is established. Finally, the simulation study based on D-S evidence theory is implemented for the structure and the algorithm of the aircraft ground power fault integration, which achieves satisfied results.
