Control of Synchronous Motors
Synchronous motors are indubitably the most effective device to drive industrial production systems and robots with precision and rapidity. Their control law is thus critical for combining at the same time high productivity to reduced energy consummation. As far as possible, the control algorithms must exploit the properties of these actuators. Therefore, this work draws on well adapted models resulting from the Park’s transformation, for both the most traditional machines with sinusoidal field distribution and for machines with non-sinusoidal field distribution which are more and more used in industry. Both, conventional control strategies like vector control (either in the synchronous reference frame or in the rotor frame) and advanced control theories like direct control and predictive control are thoroughly presented. In this context, a significant place is reserved to sensorless control which is an important and critical issue in tomorrow’s motors.
Direct Eigen Control for Induction Machines and Synchronous Motors
Clear presentation of a new control process applied to induction machine (IM), surface mounted permanent magnet synchronous motor (SMPM-SM) and interior permanent magnet synchronous motor (IPM-SM) Direct Eigen Control for Induction Machines and Synchronous Motors provides a clear and consise explanation of a new method in alternating current (AC) motor control. Unlike similar books on the market, it does not present various control algorithms for each type of AC motor but explains one method designed to control all AC motor types: Induction Machine (IM), Surface Mounted Permanent Magnet Synchronous Motor (SMPM-SM) (i.e. Brushless) and Interior Permanent Magnet Synchronous Motor (IPM-SM).

New Adventures in Language and Interaction
In this book sixteen international scholars of language and social interaction describe their distinct frameworks of analysis. Taking conversation analysis and interactional sociolinguistics as their points of departure and investigating ordinary conversation as well as institutions such as health care, therapy, and city council meetings, they often incorporate gesture, prosody, and the listener's behavior in the analysis of talk. While some approaches are grounded in a critique of the major schools of interaction analysis, others integrate the interactionist perspective with ideas from fields such as systemic-functional linguistics, distributed cognition, and the sociology of knowledge. Each chapter combines a statement of the terms and methods of analysis with an exemplary analysis of a moment of interaction. "New Adventures in Language and Interaction" gives an excellent overview of the novelty and diversity of interaction-focused perspectives on language and of the heterogeneity of approaches that have evolved from the pioneering work of Sacks and Schegloff, Gumperz, and their co-workers.
Fifty Key Sociologists: The Contemporary Theorists
Fifty Key Sociologists: The Contemporary Theorists covers the life, work, ideas and impact of some of the most important thinkers in this discipline. Concentrating on figures writing predominantly in the second half of the twentieth century, such as Zygmunt Bauman, Pierre Bourdieu, Judith Butler, Michel Foucault and Claude Lévi-Strauss, each entry includes: full cross-referencing a further reading section biographical data key works and ideas critical assessment. Clearly presented in an easy-to-navigate A–Z format, this accessible reference guide is ideal for undergraduate and postgraduate students of sociology, cultural studies and general studies, as well as other readers interested in this fascinating field.
Handbook of the Sociology of Morality
Human beings necessarily understand their social worlds in moral terms, orienting their lives, relationships, and activities around socially-produced notions of right and wrong. Morality is sociologically understood as more than simply helping or harming others; it encompasses any way that individuals form understandings of what behaviors are better than others, what goals are most laudable, and what "proper" people believe, feel, and do. Morality involves the explicit and implicit sets of rules and shared understandings that keep human social groups intact. Morality includes both the "shoulds" and "should nots" of human activity, its proactive and inhibitive elements. At one time, sociologi...
The Oxford Handbook of Linguistic Fieldwork
This book offers a state-of-the-art guide to linguistic fieldwork, reflecting its collaborative nature across the subfields of linguistics and disciplines such as astronomy, anthropology, biology, musicology, and ethnography. Experienced scholars and fieldworkers explain the methods and approaches needed to understand a language in its full cultural context and to document it accessibly and enduringly. They consider the application of new technological approaches to recording and documentation, but never lose sight of the crucial relationship between subject and researcher. The book is timely: an increased awareness of dying languages and vanishing dialects has stimulated the impetus for recording them as well as the funds required to do so. The handbook is an indispensible source, guide, and reference for everyone involved in linguistic and cultural work.
Modelling and Control of Electrical Machines
Hardbound. This collection from the Third International IMACS Symposium constitutes a source of new ideas for engineers and scientists working in the field of electrical drives or developing new applications of electrical machines. Papers are included addressing such subjects as electrical machines, design and operation of electrical drives, and simulation software. Additionally, a number of special problems such as thermal phenomena, iron losses and power systems are explored.
Analysis and Design of Multicell DC/DC Converters Using Vectorized Models
Shows how the concepts of vectorization and design masks can be used to help the designer in comparing different designs and making the right choices. The book addresses series and parallel multicell conversion directly, and the concepts can be generalized to describe other topologies.
Morphopragmatics
TRENDS IN LINGUISTICS is a series of books that open new perspectives in our understanding of language. The series publishes state-of-the-art work on core areas of linguistics across theoretical frameworks, as well as studies that provide new insights by approaching language from an interdisciplinary perspective. TRENDS IN LINGUISTICS considers itself a forum for cutting-edge research based on solid empirical data on language in its various manifestations, including sign languages. It regards linguistic variation in its synchronic and diachronic dimensions as well as in its social contexts as important sources of insight for a better understanding of the design of linguistic systems and the ecology and evolution of language. TRENDS IN LINGUISTICS publishes monographs and outstanding dissertations as well as edited volumes, which provide the opportunity to address controversial topics from different empirical and theoretical viewpoints. High quality standards are ensured through anonymous reviewing. To discuss your book idea or submit a proposal, please contact Birgit Sievert.
Advanced Control of AC / DC Power Networks
The power engineering domain is facing huge challenges, with an increasing interest in intermittent renewable energies which are imposing major technical limitations. Operating ever closer to their limits, the industry-standard AC power grids are subject to instabilities. This book presents an insight into DC grid systems, offering interesting issues to well controlled power grids, in contrast to current AC systems which provide the simplest and most economic connection method for short distances.
