DIAGNOSABILITY THEORIES IN VERIFICATION TECHNIQUES FOR ANALOG FAULT DIAGNOSIS WITH TORALENCE
-
摘要: 本文首先通過Voronoi超球面描述了故障驗證方法體系中全部特征子陣的最近鄰關(guān)系,再通過攝動理論分析了測量電壓變化陣k維最大方向能量子空間的酉基陣對故障特征子陣的偏差干擾角。然后在此基礎(chǔ)上討論了故障驗證方法體系可診性問題,導(dǎo)出了該方法體系在診斷模擬電路故障時的可診充要條件,并據(jù)可診性質(zhì)對診斷問題進行了分類界定。

Abstract: This paper descibes all nearest-neighbors relations of feature submatrices in fault verification techniques with a Voronoi hypersphere, analyses deveation disturbance angles between the feature submatrices and an unitary basis submatrix of the -dimension maximal orientation-energy subspace of a measured voltgage-change matrix through disturbance theories. Based on the above, the paper proposes novel diagnosibility theories for the system of fault verification techniques, derives a necessary and sufficient diagnosability condition in verification techniques for analog fault diagnosis under toralence disturbance. In addition, the paper classifies diagnosis problems with the revealed diagnossability. -
