Handing Tolerance Problem in Fault Diagnosis of Linear-Analogue Circuits with Accurate Statistics Approach
Figure 5
(a) Circuit fault ( or ) can de determined if the corresponding variation of nodal voltage is found in the range of , or in the range of . Furthermore, due to the data fusion between and , the fault diagnosis error of is no more than if and only if upper confidence limit of is while lower confidence limit of is . (b) The data fusion caused by the worst tolerance in a circuit.
