Abstract

We introduce the class of systems treated in the book—nonlinear discrete time control systems on metric spaces—and illustrate them by several examples. Moreover, we discuss sampled data systems as an important special case. Afterwards, we introduce the necessary background material from Lyapunov stability theory for discrete time and sampled data systems which will be needed for the stability analysis of NMPC schemes.

Strictly speaking, \(L^\infty \) functions are not even defined pointwise but rather via equivalence classes which identify all functions \(v\in L^\infty (\mathbb {R},\mathbb {R}^m)\) which coincide for almost all \(t\in \mathbb {R}\). However, in order not to overload the presentation with technicalities we prefer the slightly heuristic explanation given here.
