摘要
本文根据改进节点法和替代定理提出一种诊断非线性电阻电路多故障的方法,此方法将每个非线性电阻元件用相应的电流源替代,从而使诊断方程是线性的,诊断也较为简便。本文提出的方法适用于含有各种受控源的电路.
A method is proposed to diagnose multiple fault of nonlinear resistive circuits on the basis of the modified nodal approach and substitution the- orem.The corresponding current source is substituted for every nonlinear resistance in this method,thus fault-diagnosis equation is linear,and diagnosis procedure is simple.The method is applicable to the nonlinear resistive circuits with all kinds of controlled sources.
