为缩短航天发射时间,提高作战应急反应能力,采用模糊聚类分析的方法,建立了模糊聚类分析模型:~G及μg(ui),ui∈U.提出了用最大差值来定义两个隶属函数之间的距离,设计了一种基于模糊聚类分析的算法FJLA,有效地对实时发生的故障与历史故障进行聚类,并找出发生故障的仪器等部器件.实验结果表明,应用上述理论可将故障定位在较小的范围.对某型火箭的测试表明,有效率达64.7%.
為縮短航天髮射時間,提高作戰應急反應能力,採用模糊聚類分析的方法,建立瞭模糊聚類分析模型:~G及μg(ui),ui∈U.提齣瞭用最大差值來定義兩箇隸屬函數之間的距離,設計瞭一種基于模糊聚類分析的算法FJLA,有效地對實時髮生的故障與歷史故障進行聚類,併找齣髮生故障的儀器等部器件.實驗結果錶明,應用上述理論可將故障定位在較小的範圍.對某型火箭的測試錶明,有效率達64.7%.

In order to reduce the launch time and increase the capacity of emergency response operations,a model of fuzzy cluster analysis:G and μg (ui),ui∈U is established by using fuzzy clustering analysis,the maximum difference between the two membership functions to define the distance is presented,and a cluster analysis based on fuzzy algorithms FJLA is designed,effective real-time and historical fault occurred cluster failure and failure to identify devices,equipment and so on.Experimental analysis shows applying the theory the proposed of the fault location is reduced and the effective rate is 64.7% in a application test of rocket.
