Compared with the traditionalroot-locus method, the root-locus method proposed in this dissertation has thefollowing characters:1 The poles location is expressed by polar coordinates.2 The poles location is computed directly.3 The object includes the closed-loop systems and controllers.4 The influence of the parameters on the polar radius and angle can be studied mainly by differential operation.5 The relationship between the polar radius and angle can be studied mainly by differential operation.

与传统的根轨迹法相比，本论文中所采用的根轨迹法具有以下的特点：1 使用极坐标表示极点的位置2 直接计算闭环极点的分布3 研究对象包括闭环系统与控制器4 以微分运算为主要手段，研究了参量的变化对极点的极径和辐角的影响5 以微分运算为主要手段，研究了极点的极径与辐角间的关系本论文从研究Dahlin 控制器振铃现象的成因及消除方法出发，主要进行了以下方面的研究：运用根轨迹法对Dahlin 控制器进行了动态性能分析。
