用伴随网络法系统求解网络多端口一阶灵敏度

SYSTEMATIC CALCULATION NETWORK MULTIPORTS ONE-ORDER SENSITIVITIES BY THE ADJOINT NETWORK METHOD

本文提出用稀疏表格法建立多端口伴随同络混合参数矩阵,进而构成了一个有规则的矩阵关系式,可一次求取计算网络多端口一阶灵敏度所需要的支路变量信息。在此基础上,定义了一个矩阵循环乘概念,并给出了系统求解网络多端口输出相对每个元件参数变化的一阶灵敏度公式。

In this paper,the sparse tableau approach is used to build multiportsadjoint network mixed parameters matrix,thus conducting a matrix relation formula.Branch variables required in calculating one-order sensitivities of multiports network areobtained one time.Based on this,the concept of the matrix loop multiple is defined.Atthe same time,the calculating formula of one—order sensitivities of network multiports out-put is given with respect to each parameter hanges.
