The notions of passivity and positive realness are fundamental concepts in classical control
theory, but the use of the terms has varied. For LTI systems, these two concepts capture the …

A central notion in systems theory is dissipativity, which was introduced by Jan Willems with
the explicit goal of arriving at a fundamental understanding of the stability properties of …

(I. la) m= f (x)+[gi (x) ui i= I (1. lb) y= h (x) and we want to examine to what extent the behavior
of such a system could be made" linear" under the effect of an appropriate feedback control …

l\lany systems encountered in practice involve a coupling between contin uous dynamics
and discrete events. Systems in which these two kinds of dynamics coexist and interact are …

In this chapter we present a state space interpretation of the small gain and passivity
approach of the previous chapter. Moreover, we will come to some kind of synthesis …

The output regulation problem, or alternatively, the servomechanism problem, addresses
design of a feedback controller to achieve asymptotic tracking for a class of reference inputs …

Constructive Nonlinear Control presents a broad repertoire of constructive nonlinear
designs not available in other works by widening the class of systems and design tools …

In this paper, we derive conditions under which a nonlinear system can be rendered passive
via smooth state feedback and we show that, as in the case linear systems, this is possible if …

This paper addresses the issues of stability, L2-gain analysis and H∞ control for switched
systems via multiple Lyapunov function methods. A concept of general Lyapunov-like …

In the early days of nonlinear control theory most of the stability, optimality and uncertainty
concepts were descriptive rather than constructive. This survey describes their …
