Parameter Space Design

With Chapter 11 we are entering into Part IV of this book, the part that deals with design. For an uncertain closed-loop characteristic polynomial p(s, q, k) we want to find a k = k0 such that the polynomial p(s, q, k0) is Γ-stable for all q ∈ Q. Generic situations are:1. There exists such a k0 and also a neighborhood KΓ of k0 has the same property, see Fig. 3.10. We want to pick the “best” k ∈ KΓ in consideration of further design requirements.
