摘要: 本文根據(jù)分布參數(shù)傳輸線理論導(dǎo)出了電纜內(nèi)平行多導(dǎo)線間串?dāng)_電壓的傳遞函數(shù)矩陣表達(dá)式;構(gòu)造了導(dǎo)線同串?dāng)_電壓最小的優(yōu)化目標(biāo)函數(shù);利用可變多面體算法進(jìn)行了優(yōu)化設(shè)計(jì);根據(jù)計(jì)算結(jié)果提出了降低申擾電壓的新方法。計(jì)算結(jié)果與已有的實(shí)驗(yàn)結(jié)果吻合。

Abstract: Based on transmission line theory, the voltage transfer ratio function matrixes are derived for the multi-conductor cable system. Then an optimising object function for reducing crosstalk in the multi-conductor cable is established. The nonlinear programming is applied to optimize the terminal impedance load. According to the optimization results, a new method for reducing crosstalk is presented. Theoretical results are in good agreement with experimental ones. -
