Due to the increasing availability of improved power electronics and digital processors at
reduced costs, there has been a trend to seek higher performance from electric machine …

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 …

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 …

A pulse-width modulated control for a class of electromechanical system models is
designed. It is shown how approximate feedback linearization, based on the integral …

A globally exponentially stabilising composite feedback control is proposed for a general
class of nonlinear singularly perturbed systems. The chosen design manifold becomes an …

Considers a class of control systems represented by nonlinear differential equations
depending on a small parameter. The systems are not in the standard singularly perturbed …

Using a geometric approach, a composite control—the sum of a slow control and a fast
control—is derived for a general class of non-linear singularly perturbed systems. A new and …

MATHEMATICAL modeling of many physical systems requires high-order dynamic
equations. The presence of parameters such as spring constant, mass, and moments of …

A class of discrete-time nonlinear systems which are two-time-scale is treated. Using the
singular perturbation theory in a systematic way, we present a mode-decoupling approach …

This paper deals with a class of two-time-scale nonlinear systems with time-varying
disturbances, modeled within the framework of singular perturbations. Systems in both …
