Plotting the Root Locus of the Dahlin Controller
Abstract: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.
