【Abstract】 This paper presents a modified method for multiple-faults diagnosis of resistance circuits with weakly nonlinear element. The method consists of two parts: multiple-faults location by solving linear diagnosis equations, and then multiple-faults identification by solving nonlinear equations. Diagnosability of the linear diagnosis equation is improved, and the occurrence of the failure of diagnosis or the presence of equivalent faults under certain circumstance by other methods may be reduced, since the characteristics of the nonlinear elements are taken into consideration while formulating the linear diagnosis equation.更多还原
