Review of Some Concepts for Linear Control Systems<br />
•If (A, B) is controllable, then ΨcΨ∗ c =: Wc is nonsingular, and the answer<br />
to the preceding question is uopt := Ψ∗ cW −1<br />
c x0. The input energy is given<br />
by ∥uopt∥2 2 = x∗0 W −1<br />
c x0.<br />
• The reachable set through uopt, i.e. the final states x0 = Ψcu that can<br />
be reached given an input u ∈ L2(−∞, 0] of unit norm,<br />
{Ψcu : u ∈ L2(−∞, 0] and ∥u∥2 ≤ 1} may be defined as<br />
R := {W 1<br />
2<br />
c xc : xc ∈ C n and ∥xc∥ ≤ 1}.<br />
