Abstract Since the mid-90's, State-Dependent Riccati Equation (SDRE) strategies have
emerged as general design methods that provide a systematic and effective means 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 …

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 …

" I believe that the authors have written a first-class book which can be used for a second or
third year graduate level course in the subject... Researchers working in the area will …

Previously obtained results on L2-gain analysis of smooth nonlinear systems are unified and
extended using an approach based on Hamilton-Jacobi equations and inequalities, and …

This book presents advances in the theory and design of robust nonlinear control systems.
In the first part of the book, the authors provide a unified framework for state-space and …

AEROSPACE engineering applications greatly stimulated the development of optimal
control theory during the 1950s and 1960s, where the objective was to drive the system …

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 …

A solution to the problem of disturbance attenuation via measurement feedback with internal
stability is presented for an affine nonlinear system. It is shown that the concept of …

We show that input-to-state stabilizability (as defined by Sontag, 1989, 1995) is both
necessary and sufficient for the solvability of a Hamilton-Jacobi-Isaacs equation associated …
