Robust control of a class of uncertain nonlinear systems
TL;DR: In this article, the robust control of a class of nonlinear systems with real-time-varying parameter uncertainty is considered and a technique is proposed for designing stabilizing controllers for both problems by converting them into scaled H∞ control problems which do not involve parameter uncertainty.
Journal ArticleDOI
Criteria for robust stability and stabilization of uncertain linear systems with state delay
Xi Li,Carlos E. de Souza +1 more
TL;DR: In this paper, the authors deal with the problem of robust stability analysis and robust stabilization for a class of uncertain linear systems with a time-varying state delay, where the uncertainty is assumed to be norm-bounded and appears in all the matrices of the state space model.
Journal ArticleDOI
H∞ estimation for discrete-time linear uncertain systems
TL;DR: In this paper, a Riccati equation approach is proposed to solve the estimation problem and it is shown that the solution is related to two algebraic Riemannian equations, and the estimation error dynamics is quadratically stable and the induced operator norm is kept within a prescribed bound for all admissible uncertainties.
Journal ArticleDOI
H∞ estimation for uncertain systems
TL;DR: In this paper, an interpolation theory approach and a Riccati equation approach are proposed to solve the estimation problem, with each method having its own advantages, the first approach seems more numerically attractive whilst the second one provides a simple structure for the estimator with its solution given in terms of two algebraic REs and a parameterization of a class of suitable H, estimators.

On the Discrete-time Bounded Real Lemma with application in the characterization of static state feedback H ∞ controllers
Carlos E. de Souza,Lihua Xie +1 more
TL;DR: In this paper, the Discrete-time Bounded Real Lemma (DRL) is used to characterize all static state feedback H ∞ controllers for non-minimal stable state-space realizations.
