用模糊聚类算法快速定位小卫星在轨运行故障

FAST LOCATING ONBOARD FAULT OF SMALL SATELLITES USING FUZZY CLUSTERING ALGORITHMS

针对小卫星在轨系统复杂、监测点众多以及测量信息固有的不确定性等特点，采用一种简化的模糊Ｃ均值聚类（ＦＣＭ）算法快速定位在轨运行故障，并以哈尔滨工业大学卫星工程技术研究所研制的立体测绘微小卫星（ＳＭＭＳ）为背景以达到实际应用的目的．

Considering the complexity of small satellites, large number of monitoringpoints and the inherent fuzziness and uncertainty of measuring information, a simplified FCM algorithm is presented in this paper to fast locate on-board fault. As onof the applications, this paper also describes the onboard fault fast locating systemof SMMS, which is a small satellite of Research institute of Satellite Engineeringand Technology of Harbin institute of Technology and will be launched in 2000.
