Abstract

The examples of Chapter 1 have in common that the plant is insufficiently damped or even unstable in its operating domain Q. Thus, a primary task of a control system is stabilization with sufficient damping for all qQ. Since eigenvalues cannot be shifted by a feedforward control system, we need a feedback structure. Fig. 2.1 shows an example of a control system with a plant family G(s,Q) = {g{s,q) |qQ}, a feedback compensator (or controller) c(s), and a feedforward path (or prefilter) Ƒ(s).
