Graphical procedure
[edit]Isn't a root locus more like a graphical procedure for determining the poles of a closed-loop system given the poles and zeros of a forward-loop system? Wetman 02:16, 15 Mar 2004 (UTC)
- No the root locus is a usefull tool for determining when the poles and zeros of our system are stable and from this we can determine what type of compensation would be needed on the system. minorproblem add missing date 12:20, 19 May 2006 (UTC)
- I believe that Wetman is not incorrect. Root Locus does find the poles, starting from the open loop. I will try to improve this page, & yes, with some graphics. I am a huge fan of root locus, surprised at the small entry here! Markrkrebs (talk) 12:13, 29 November 2007 (UTC)
- "the root locus is the locus of the poles and zeros of a transfer function as the system gain K is varied on some interval."
- This is wrong. Like the name "root locus" implies, the locus of the poles only (not the zeros) is constructed. —Preceding unsigned comment added by 134.130.45.36 (talk) 13:40, 10 November 2008 (UTC)
Example
[edit]I think that the example in this article could really be improved if it included some visual aids (at the very least a diagram of the system) 205.166.66.2 13:27, 14 August 2007 (UTC)
- I agree about adding visual aids. Also, the wording is pretty atrocious, too informal and excited. A simpler, more straightforward approach would be preferred. 18.247.5.18 (talk) 18:00, 15 November 2009 (UTC)

k values
[edit]does anyone have any idea how to plot the vector magnitudes if given a damping ratio (zeta) from the standard set of second order step responses, what is the correct procedure — Preceding unsigned comment added by 2.26.237.217 (talk) 16:11, 10 May 2013 (UTC)
Sketching section missing subtlety
[edit]When computing the asymptotes' real-axis intersection we need to use the sums of the _real-parts_ of zeros and poles. I will go ahead and change it for completeness. 87.214.162.181 (talk) 14:39, 15 September 2020 (UTC)
What is "roots"?
[edit]In the first line, "...examining how the roots of a system change..." what is "roots"? Please provide a definition and-or link to a definition or article.
