求线性定常控制系统传递函数的几种方法

Discussions on Several Methods of Transfer Function of Linear Time-invariant Control Systems

本文总结了求线性定常控制系统传递函数常用的几种方法:梅逊公式法,方块图化简法,拉氏变换法以及变换阻抗法等,针对一般教材中对以上各方法研究的不足,特别是对于梅逊公式的两种情况间的联系以及方块图化简中较复杂的变换-移动引出点使之越过比较点这一变换作了必要的补充。

Some methods which can work out the transfer functions of linear time-invariant control systems are summarized. They are Mason Formula,Diamonds-figure Redigestion,Laplace Transformation and Transformation Impedance.As for the deficiencies of those methods some necessary supplements are given in the paper.
