So, if I have a unity feedback controller with transfer function
\(G_p(s) = \frac{K(s+1)}{s^2(s+9)}\)
Is my root loci going to be of \(G_p(s)\) OR is it of
\(T(s) = \frac{G(s)}{1+KG(s)} = \frac{s+1}{s^3+9s^2+Ks+K}\)
?
That's my question. Now, it seems more likely it's the first one, since why would we be told to graph the root loci of a graph with unobtainable poles...
And, if that is the case, does that mean to graph the root loci of a non-unity feedback controllers do I need to convert it to a form that resembles a unity feedback controller?
Thanks a lot guys,
