利用降阶改进节点法列写非线性有源电阻网络方程

Use Reduced Modified Nodal Approach to Formulate Equations of Non-Linear Active Resistant Networks

本文利用降阶改进节点法(RMNA)列写非线性电阻网络方程,网络中可包含压控/流控型非线性电阻和四种非线性的受控源,文中利用了降阶技术和矩阵行列重序技术,能直接列写降阶改进节点方程;在编程技术方面,将改进的牛顿迭代法与函数调用相结合,解决了非线性函数的输入与转移问题。

The Reduced Modified Nodal/(?) proach is applied to formulate the equations of nonlinear active resistant (?)etworks, in which voltage controlled resistances, current controlled resistances and four kinds of nonlinear dependent sources are included. In this paper, the techniques of oder reducing and renumbering of rows and columns of matrices are used to formulate Reduced Modified Nodal Equations directly. In respect of programming, the improved Newton iteration algorithm is associated with function designations, therefore input and transfer of nonlinear functions are solved.
