WebThe root locus plot is a relatively simple tool for obtaining, by graphical means, detailed informa- tion about the stability of a closed-loop system knowing only the open-loop transfer function. The plot shows the roots, or poles, of the closed-loop system characteristic equation for every value of a single-loop variable, typically the feedback gain.

WebControl Systems Root Locus - In the root locus diagram, we can observe the path of the closed loop poles. Hence, we can identify the nature of the control system. In this … WebThe closed loop poles are roots of the characteristic equation for the closed loop system = P (s).V (s) + K.Q (s)W (s) = 0 Generally the location of these roots in the s plane changes as the gain factor K is altered. The root locus is the locus of these roots as a function of K. flutie or williams crossword
