This book is about stability analysis and control design methodologies for a new class of systems, switched time-delay systems (STDs). Adopting a systematic and structured approach, the author presents an introductory, yet comprehensive, treatment of STDs.

In many practical applications we deal with a wide class of dynamical systems that are comprised of a family of continuous-time or discrete-time subsystems and a rule orchestrating the switching between the subsystems. This class of systems is frequently called switched system. Switched linear systems provide a framework that bridges the linear systems and the complex and/or uncertain systems. The mo- vation for investigating this class of systems is twofold: ?rst, it has an inherent multi-modal behavior in the sense that several dynamical subsystems are required to describe their behavior, which might depend on various environmental factors. Second, the methods of intelligent control systems are based on the idea of swit- ing between different controllers. Looked at in this light, switched systems provide an integral framework to deal with complex system behaviors such as chaos and multiple limit cycles and gain more insights into powerful tools such as intelligent control, adaptive control, and robust control. Switched systems have been inves- gated for a long time in the control and systems literature and have increasingly attracted more attention for the past three decades. The number of journal articles, books, and conference papers have grown exponentially and a number of fundam- tal concepts and powerful tools have been developed. It has been pointed out that switched systems have been studied from various viewpoints.

From the reviews:

"The monograph presents an introduction in the Lyapunov stability and control issues for switched time-delay systems. ... It is a comprehensive up-to-date authoritative reference presenting systematically the Lyapunov stability, control, and filtering issues with complete mathematical proofs and illustrative examples. The book is primarily intended for researchers, engineers, and advanced postgraduate students working in switched time-delay systems and other related areas." (Lubomír Bakule, Zentralblatt MATH, Vol. 1229, 2012)

"The book is mostly devoted to the stability problems and related topics (stabilization, control, and filtering). ... The book is clearly written: the most important ideas are usually explained in ... simple situations. Various parts of the book can be read to a large extent independently. The book may serve both as an introduction to the subject and as an exposition of recent results." (V. G. Kurbatov, Mathematical Reviews, Issue 2012 h)
