Dahlin控制器的根轨迹的绘图方法

对Dahlin控制器的控制机理进行了重新阐述。利用矢量分析方法，计算 Dahlin控制器的根轨迹的入射角。研究Dahlin控制器的极点的极径和极径与正实轴夹角的相互关系。提出 Dahlin控制器的根轨迹的计算机绘图方法。此外，可以利用作图的方法，确定Dahlin控制器的复数极点的位置。

Plotting the Root Locus of the Dahlin Controller

The control mechanism of the Dahlin controller was represented. Using the vector analysis method, the arrival angle of the root locus of the Dahlin controller was calculated. The relationship between the polar radius and the angle between the polar radius and the positive axis of the poles of the Dahlin controller was studied. A computer graphical method was proposed to plot the root locus of the Dahlin controller. Moreover, the positions of the complex poles of the Dahlin controller can be determined by a graphical method.
