I have a good basic understanding on classical control theory. Now I am studying modern control theory.I encountered the following equations as seen below.
Online I have only been able to find representation of differential equations in the form on these equations.
Im more interested in the background (or derivation) of these equations themselves or atleast some background on from where these equations came about, I dont want to accept them as is.
If my question too rudimentary, please know im just starting out in this subject. Thanks!
