[PDF][PDF] Singular perturbations and time scales in control theory and applications: an overview

D Naidu - Dynamics of Continuous Discrete and Impulsive …, 2002 - researchgate.net
A basic problem in the control system theory is the mathematical modeling of a physical
system. The modeling of many systems calls for high-order dynamic equations. The …

Singular perturbations and input-to-state stability

PD Christofides, AR Teel - IEEE Transactions on Automatic …, 1996 - ieeexplore.ieee.org
This paper establishes a type of total stability for the input-to-state stability property with
respect to singular perturbations. In particular, if the boundary layer system is uniformly …

Robust stability of two-time-scale systems with nonlinear uncertainties

ZH Shao - IEEE Transactions on Automatic Control, 2004 - ieeexplore.ieee.org
This note is concerned with the robust stability problem of uncertain two-time-scale systems,
where the only information available for system uncertainties is their norm upper bounds …

Feedback control of two-time-scale nonlinear systems

PD Christofides, P Daoutidis - International Journal of Control, 1996 - Taylor & Francis
This article concerns a class of two-time-scale single-input single-output nonlinear systems.
For such systems, combination of singular perturbation and geometric methods is employed …

H/sub 2/guaranteed cost control for singularly perturbed uncertain systems

G Garcia, J Daafouz… - IEEE transactions on …, 1998 - ieeexplore.ieee.org
The H/sub 2/guaranteed cost control problem for a singularly perturbed norm-bounded
uncertain system is addressed using the quadratic stabilizability framework. After defining …

Stabilisation of uncertain singularly perturbed systems

ZH Shao, ME Sawan - IEE Proceedings-Control Theory and Applications, 2006 - IET
This note studies the robust stabilisation problem of a linear time–invariant singularly
perturbed system with nonlinear uncertainties, where the only information available for …

Robust semi-global output tracking for nonlinear singularly perturbed systems

PD Christofides, AR Teel… - International Journal of …, 1996 - Taylor & Francis
In this work, a robust controller design methodology for a broad class of singularly perturbed
nonlinear systems with time-varying uncertainties is developed. When the fast subsystem is …

Multivariable circle criteria for multiparameter singularly perturbed systems

HD Tuan, S Hosoe - IEEE Transactions on Automatic Control, 2000 - ieeexplore.ieee.org
A direct approach to the Lur'e problem for singularly perturbed systems (SPS) is proposed.
In contrast to previous results, the feedback connection between the linear and nonlinear …

Robust control of multivariable two-time-scale nonlinear systems

PD Christofides, P Daoutidis - Journal of Process Control, 1997 - Elsevier
This paper focuses on the synthesis of well-conditioned multivariable robust controllers for a
broad class of multi-input multi-output two-time-scale nonlinear systems with time-varying …

Robust stability of nonlinear singularly perturbed system with uncertainties

JW Son, JT Lim - IEE Proceedings-Control Theory and Applications, 2006 - IET
The singularly perturbed system is easily analysed by two time-scale systems, each of which
with a lower dimension than the original system. However, if uncertainties are added, then …
