Transfer functions of regular linear systems. I. Characterizations of regularity
We recall the main facts about the representation of regular linear systems, essentially that they can be described by equations of the form <inline-formula content-type="math/mathml"> <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" alttext="ModifyingAbove x With dot left-parenthesis t right-parenthesis equals upper A x left-parenthesis t right-parenthesis plus upper B u left-parenthesis t right-parenthesis"> <mml:semantics> <mml:mrow> …
