A New Approach of Simultaneous Faults Diagnosis Based on DSmT
Chenglin Wen · Journal of Hangzhou Dianzi University · 2008
In order to solve the simultaneous faults problems,a new approach based on the Dezert-Smarandache theory(DSmT) is proposed in this paper.Firstly,the simultaneous faults' model is built based on the generalized frame of discernment in DSmT.Secondly,according to the working characteristics and environment of the sensors used to acquire fault characteristic information,a new method to construct basic probability assignment function is proposed based on membership function.Finally,a case study pertaining to the fault diagnosis for a multi-function rotor test-bed is given,and the results show that the proposed diagnosis approach is feasible and efficient.
