Talk:Closed-loop pole

Formula
i'm pretty sure there's an error with the formula of the open loop transfer function. The open-loop transfer function is the transfer function between the input and the feedback signal if the connection of the feedback were opened. This means that it should be KGH not just KG as stated in the article

Why are "poles" called that?
In the first sentence, "Closed-loop poles are the positions of the poles (or eigenvalues)..."; 1. If poles are eigen-values, why are they suddenly called "poles." 2. Eigen-values are scalars, they don't have positions, so how does that part of the sentence even make sense? Michael Hodgson (talk) 03:26, 17 September 2021 (UTC)
