FAST LOCATING ONBOARD FAULT OF SMALL SATELLITES USING FUZZY CLUSTERING ALGORITHMS
-
摘要: 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。Abstract: 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 on of 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.
