A Method for Searching the Root Loci by Computer in the Half Complex Plane
-
摘要: 本文介绍一种用电子计算机计算根轨迹的方法,称为半平面搜索法.其几何意义是,在复 平面上作一系列平行于虚轴的直线,用计算机求解这一系列直线与根轨迹的交点.由于根轨 迹方程中未出现可变增益K,从而使计算大为简化.比传统的伊文思法要简便准确得多.Abstract: In this paper a method for searching the root loci by the computer is presented. The geometrical concept is to make a lot of parallel lines of the imaginary axis in the complex plane, and to decide the points which satisfy both the root loci and the parallel lines by the computer. The computation will be simplified, since the variable gain K would not appear in the equation of the root loci.
