Graphical procedure

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

Example

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)[reply]

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)[reply]

"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)[reply]
