Singular perturbations and time-scale techniques were introduced to control engineering in the late 1960s and have since become common tools for the modeling, a

This book results from various lectures given in recent years. Early drafts were used for several single semester courses on singular perturbation meth ods give

This book is devoted solely to the boundary function method, which is one of the asymptotic methods.

This book presents the twin topics of singular perturbation methods and time scale analysis to problems in systems and control. The heart of the book is the sin

Describes, analyzes, and generalizes the principal results concerning perturbation methods in optimal control for systems governed by deterministic or stochasti
