This article describes how to sketch root loci by using computers.Compared with the common rules of the construction of root loci, computer-aided construction has the following features. 1.Root loc: are sketched not in accordance with the basic rules of the construction of root loci, but in light of the characteristic equation of a system and by use of the numerical method; 2.As the poles of the closed-loop system are calculated by the computer, the roots of higher equation can be derived exactly, so that it is easier to sketch the root loci of higher-order system; 3.The flexibility of the programs helps to sketch root locus diagrams both complete and over a certain range. An example is given in the article.

本文直接从控制系统特征方程出发,说明了如何应用计算机来绘制根轨迹。它与通常根轨迹绘制基本规则比较,主要差异在于:1.根据系统特征方程采用数值方法而不是按绘制根轨迹的基本规则来绘制根轨迹;2.通过计算机计算来计算闭环极点,可以比较准确地求出高次方程的根,因而在绘制高阶系统根轨迹时也较方便;3.利用所编程序灵活性,既可给出完整根轨迹图,同时又可绘出某确定范围内的根轨迹图并加以放大,以利分析与设计。文中利用此法给出了一个实例,从而为绘制控制系统根轨迹图提出了一种较合理的途径。
