Control 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 technique, we will use an open loop transfer function to know the stability of th
The designer can then select a value of this parameter so as to position the closed-loop poles at appropriate positions in the plane. Most importantly of all, perhaps, this locus of all possible closed-loop pole positions can be derived from a knowledge of the open-loop transfer function ...
Question: Sketch the root locus for the unity feedback control system whose open-loop transfer function is given. G(s)H(s) = K Determine s(s+4)(s2 +4s+20) a) The breakaway and break-in points b) The intersection of root locus with jo...

root locus plot [′rüt ¦lō·kəs ‚plät] (control systems) A plot in the complex plane of values at which the loop transfer function of a feedback control system is a negative number. McGraw-Hill Dictionary of Scientific & Technical Terms, 6E, Copyright © 2003 by The McGraw...
This symmetry is reflected in the root locus plot. c) Starting and ending points: The starting points of the root locus branches are the poles of the open-loop transfer function, while the ending points are the zeros of the open-loop transfer function. In this case, the op...
