中文摘要：

以故障可诊断性,即可检测性和可分离性为目标进行测点配置方法研究。针对航天器部件测点较多,传统基于有向图（directed graph,DG）的方法在偶图绘制非常复杂且容易出错的情况,引入关联矩阵描述处理可诊断性测点配置方法,关联矩阵方法便于应用计算机编程,且在节点较多时便于扩展。在基于DG可诊断性测点配置方法思路的基础上,对应了关联矩阵与DG二者之间的转化关系,并以动量轮为例进行基于可诊断性的测点配置。结果表明该方法对卫星部件级测点配置具有实用价值。

英文摘要：

This paper accomplishes the study of sensor location satisfying the diagnostic criteria which in- clude detectability and isolability. Traditionally, the directed graph （DG） is used in the sensor location satisfying the diagnostic criteria. However, in most cases, the spacecraft components are complex and the roots are too excessive. It is hard to develop the bipartite graph when using the DG method. So a description using the incidence matrix is put forward, which is easy to program and extend. At the meantime, the transition relation- ship between the bipartite graph and the incidence matrix is presented. Finally, the sensor location problem based on the diagnostic criteria of the fly wheel is resolved. The results demonstrate that the method is valuable for sensor location of spacecraft components.
