簡介：中國科學技術大學博士學位論文基于證據理論的在軌航天器故障診斷方法研究姓名梁偉光申請學位級別博士專業(yè)導航、制導與控制指導教師王永周建亮201105摘要II驗進行驗證。本文第五章選用了協(xié)同工作類故障和振動發(fā)散類故障兩類有代表性故障進行實驗研究。其中，協(xié)同工作類故障的實驗數據采用航天實測數據，振動發(fā)散類故障的數據選用具有代表性的隔振系統(tǒng)振動發(fā)散類故障數據。分別從故障表現(xiàn)、證據生成、融合診斷等方面對診斷過程加以實現(xiàn)，并根據振動發(fā)散類故障診斷過程中出現(xiàn)的傳感器數據傳輸出錯的問題進行了容錯性改進，設計了證據重構方法。未備案故障的診斷具有重要意義，但利用現(xiàn)有的證據理論融合診斷框架無法實現(xiàn)對未備案故障的診斷。本文第六章對利用證據理論診斷未備案故障的問題進行了探索性研究。首先分析了未備案故障的證據表現(xiàn)形式，進而選取開放世界思想和證據折扣方法形成了融合診斷機理。分別考慮故障焦元無交集和有傳遞性交集的兩種情況，對開放框架下的折扣融合過程進行理論推導，并設計仿真實驗驗證了方法在診斷未備案故障方面的有效性與合理性。關鍵詞關鍵詞證據理論故障診斷信息融合在軌航天器信息熵診斷窗口協(xié)同工作振動發(fā)散未備案故障開放診斷框架證據折扣
