Chaos Analysis and Chaotic EMI Suppression of DC-DC Converters

By: Bo Zhang,Xuemei Wang

Introduces chaos theory, its analytical methods and the means to apply chaos to the switching power supply design DC-DC converters are typical switching systems which have plenty of nonlinear behaviors, such as bifurcation and chaos. The nonlinear behaviors of DC-DC converters have been studied heavily over the past 20 years, yet researchers are still unsure of the practical application of bifurcations and chaos in switching converters. The electromagnetic interference (EMI), which resulted from the high rates of changes of voltage and current, has become a major design criterion in DC-DC converters due to wide applications of various electronic devices in industry and daily life, and the question of how to reduce the annoying, harmful EMI has attracted much research interest. This book focuses on the analysis and application of chaos to reduce harmful EMI of DC-DC converters. After a review of the fundamentals of chaos behaviors of DC-DC converters, the authors present some recent findings such as Symbolic Entropy, Complexity and Chaos Point Process, to analyze the characters of chaotic DC-DC converters. Using these methods, the statistic characters of chaotic DC-DC converters are extracted and the foundations for the following researches of chaotic EMI suppression are reinforced. The focus then transfers to estimating the power spectral density of chaotic PWM converters behind an introduction of basic principles of spectrum analysis and chaotic PWM technique. Invariant Density, and Prony and Wavelet analysis methods are suggested for estimating the power spectral density of chaotic PWM converters. Finally, some design-oriented applications provide a good example of applying chaos theory in engineering practice, and illustrate the effectiveness on suppressing EMI of the proposed chaotic PWM. Introduces chaos theory, its analytical methods and the means to apply chaos to the switching power supply design Approaches the subject in a systematic manner from analyzing method, chaotic phenomenon and EMI characteristics, analytical methods for chaos, and applying chaos to reduce EMI (electromagnetic interference) Highlights advanced research work in the fields of statistic characters of nonlinear behaviors and chaotic PWM technology to suppress EMI of switching converters Bridges the gap between numerical theory and real-world applications, enabling power electronics designers to both analyze the effects of chaos and leverage these effects to reduce EMI

Adaptive Identification and Control of Uncertain Systems with Non-smooth Dynamics

By: Jing Na,Qiang Chen,Xuemei Ren

Adaptive Identification and Control of Uncertain Systems with Nonsmooth Dynamics reports some of the latest research on modeling, identification and adaptive control for systems with nonsmooth dynamics (e.g., backlash, dead zone, friction, saturation, etc). The authors present recent research results for the modelling and control designs of uncertain systems with nonsmooth dynamics, such as friction, dead-zone, saturation and hysteresis, etc., with particular applications in servo systems. The book is organized into 19 chapters, distributed in five parts concerning the four types of nonsmooth characteristics, namely friction, dead-zone, saturation and hysteresis, respectively. Practical experiments are also included to validate and exemplify the proposed approaches. This valuable resource can help both researchers and practitioners to learn and understand nonlinear adaptive control designs. Academics, engineers and graduate students in the fields of electrical engineering, control systems, mechanical engineering, applied mathematics and computer science can benefit from the book. It can be also used as a reference book on adaptive control for servo systems for students with some background in control engineering. - Explains the latest research outputs on modeling, identification and adaptive control for systems with nonsmooth dynamics - Provides practical application and experimental results for robotic systems, and servo motors

The Promise of Digital Publishing

By: Bill Martin,Xuemei Tian

How are businesses responding to global changes in markets driven by changes in technology? Whatever the industry, the trends are familiar: globalization and the rise of industrial conglomerates, mergers and acquisitions, the networking of businesses and markets, outsourcing and shifts in the distribution of resources and production, all reflected in the emergence of new players, new products and services and new forms of competition. As arguably the first knowledge-based business, book publishing provides an ideal setting for the study of challenge and opportunity. The industry is currently experiencing fierce levels of competition, extreme financial pressures, restructuring and the threat of technology-induced obsolescence. Added to these are the challenges posed by new and potential entrants to the market, the emergence of new products and services, new ways of doing business, including trading in virtual markets, and the vulnerability of traditional business models. The suitability of book publishing as a context for researching the emergence of knowledge-based business becomes all too apparent. Through combining primary research with secondary analysis drawn from the relevant literatures, Books, Bytes and Business is both a readable and informative account of business in the knowledge-based economy.

Architecture, Ritual and Cosmology in China

The Buildings of the Order of the Dong

By: Xuemei Li

Drawing on the author’s extensive fieldwork in the Dong areas in southwest China, this book presents a detailed picture of the Dong’s buildings and techniques, with new insights into the Dong’s cosmology and rituals of everyday life meshed with the architecture, and the symbolic meanings. It examines how the buildings and techniques of the Dong are ordered and influenced by the local culture and context. The timber bridges and drum towers are the Dong’s most prominent architectural monuments. Usually built elaborately with multiple roofs, these bridges and drum towers were designed and maintained by the local carpenters who also built the village suspended houses, in an oral tradition carried down from father to son or to apprentice. They were funded entirely by the local people, and the bridges tend to be built in places without great pressure of traffic or another bridge already existing close by. Why does such great expense go into the Dong’s buildings with elaboration? How were they built? And what do they mean to their users and builders? This book is an anthropological study on the Dong’s architecture and technique, and it aims to contribute a discourse on the interdisciplinary research area. It is suitable for graduate and postgraduate readers.
