Rules for Plotting Root Locus - Root Locus Technique - Control Systems

[@Dev-wl7ej]

Also the open loop transfer function can never be denoted by G(s)H(s). Because G(s) is indeed the open loop transfer function but H(s) is Feedback transfer function and the moment you are introducing H(s) it becomes a closed loop transfer function.

Moreover if the roots are varying with respect to K then those roots are referred to as closed loop poles. You only mentioned in your previous video of Root Locus. So if the value of K increased tge root loci moves away from the poles and zeros. This is what your Rule 6 states. Then Sigma P will be Summation of all poles of CLTF

I think your rules are incorrect because here you are mentioning open loop poles whereas root locus are used to analyze the behavior of closed loop system.
