La transition vers des usages propres et pérennes de l’énergie nécessite de développer des outils et des méthodes permettant d’étudier les objets électrotechniques afin d’assurer leur bon fonctionnement, et ce, le plus longtemps possible. Il faut pour cela disposer d’outils permettant d’appréhender leurs comportements, en tant que composant, mais aussi dans les systèmes où ils se trouvent, sur l’ensemble de leur cycle de vie. Machines synchrones à double excitation présente les outils nécessaires aux chercheurs, aux étudiants et aux ingénieurs en génie électrique pour analyser le fonctionnement des machines synchrones sur l’ensemble du plan d’opération. L’accent est mis sur les machines synchrones à double excitation (MSDE). La thématique des MSDE permet d’apporter des réponses à des problématiques fondamentales telles que le « défluxage » des machines à aimants permanents, l’optimisation énergétique, et enfin l’augmentation du coût des aimants permanents.

Our transition towards a cleaner and more sustainable future has seen an increase in the use of electrical energy in the functioning of our society. This implies the need to develop tools and methods which allow us to study electromagnetic devices and ensure their functioning for as long as possible. This requires us to use these tools to understand their behavior, not just as one component, but also in the entire systems in which they can be found, throughout their life cycle. This book provides electrical engineering students and researchers with the resources to analyze how synchronous machines behave over their entire field of operation, particularly focusing on hybrid excited synchronous machines (HESMs). The field of HESMs, although not a fundamental problem in the strict sense of the term, provides answers to a range of fundamental problems: the flux weakening of permanent magnet machines, energy optimization, and lastly the increasing costs of rare-earths permanent magnets.

Classical synchronous motors are the most effective device to drive industrial production systems and robots with precision and rapidity. However, numerous applications require efficient controls in non-conventional situations. Firstly, this is the case with synchronous motors supplied by thyristor line-commutated inverters, or with synchronous motors with faults on one or several phases. Secondly, many drive systems use non-conventional motors such as polyphase (more than three phases) synchronous motors, synchronous motors with double excitation, permanent magnet linear synchronous motors, synchronous and switched reluctance motors, stepping motors and piezoelectric motors. This book presents efficient controls to improve the use of these non-conventional motors. Contents 1. Self-controlled Synchronous Motor: Principles of Function and Simplified Control Model, Francis Labrique and François Baudart. 2. Self-controlled Synchronous Motor: Dynamic Model Including the Behavior of Damper Windings and Commutation Overlap, Ernest Matagne. 3. Synchronous Machines in Degraded Mode, Damien Flieller, Ngac Ky Nguyen, Hervé Schwab and Guy Sturtzer. 4.

This book is a comprehensive set of articles reflecting the latest advances and developments in mathematical modeling and the design of electrical machines for different applications. The main models discussed are based on the: i) Maxwell–Fourier method (i.e., the formal resolution of Maxwell’s equations by using the separation of variables method and the Fourier’s series in 2-D or 3-D with a quasi-Cartesian or polar coordinate system); ii) electrical, thermal and magnetic equivalent circuit; iii) hybrid model. In these different papers, the numerical method and the experimental tests have been used as comparisons or validations.

With the growing interest in electrical machines in recent times, the multiphase machine field has developed into a fascinating research area. Their intrinsic features (power splitting, better fault tolerance, or lower torque ripple) make them an appealing competitor to conventional three-phase machines. Multiphase electric drives have been recently used in applications where fault tolerance and continuous operation of the drive are required. However, the difficulties in extending the three-phase conventional current regulation and control structure to multiphase systems still limit their broad applicability in industry solutions. The main objective of this book is to illustrate new advances, developments, and applications in the field of multiphase machines and drives, while exposing these advances, developments, and applications to the scientific community and industry.

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.

This book addresses term variation which has been a very important topic in terminology, computational terminology and natural language processing for up to twenty years. This book presents the first complete inventory of term variants and the linguistic procedures that lead to their formation. It also takes into account issues raised by multilingual applications and presents ways to detect variants in five different languages: French, English, German, Spanish and Russian. The book provides insights into the following issues: What is a variant? What are the main linguistic mechanisms involved in the transformation of base terms into variants? How can variants be automatically detected in texts? Should variation be taken into account in natural language processing applications? This book is targeted at terminologists and linguists interested in term variation as well as researchers in natural language processing and computer science that must handle term variants in different kinds of applications.

Ce volume consacré aux machines électriques englobe également l'étude du trans- formateur. Si la construction et le dimensionnement des machines électriques restent l'apanage d'un nombre restreint de spécialistes, leur emploi dans de multiples domaines et dans une gamme de puissances étalée de quelques mW à plusieurs centaines de MW touche un large public d'ingénieurs et de techniciens de diverses disciplines. Pour cette raison le Département d'Electricité de l'Ecole polytechnique fédérale de Lausanne conti- nue d'attribuer une large place à l'enseignement de cette matière. Le présent volume, tout en constituant un ouvrage de référence pour l'homme du métier, se veut à vocation essentiellement didactique à l'usage des candidats- ingénieurs en électrotechnique. Si certains développements peuvent apparaître exagérément détaillés, compte tenu de la littérature scientifique existante, leur inclu- sion dans l'ouvrage résulte de l'expérience acquise par l'auteur, confronté pendant 25 ans d'enseignement à des difficultés d'assimilation de la part des étudiants relati- ves à certains phénomènes de base (champ tournant, origine du couple électromagné- tique) ou certaines méthodes de calcul (matrices de transformation, théorie à deux axes, etc.). Le but assigné étant la présentation de la théorie de fonctionnement des machines électriques en régime transitoire ou permanent, les indications sur les maté- riaux et la morphologie ont été réduites au minimum nécessaire à la compréhension de la constitution spécifique de chaque type. De même, les essais n'ont fait l'objet que d'une description succincte. Afin de conserver à l'ouvrage une taille raisonnable, on a renoncé à un traite- ment complet des phénomènes transitoires par la transformation de Laplace ou les méthodes de calcul numérique et retenu seulement, à titre d'application des relations de base, le calcul détaillé des valeurs initiales de courants et de couples de court-circuit. La méthode consistant à négliger, dans un premier temps, l'amortissement est intéres- sante au plan pédagogique par l'entraînement qu'elle procure au bon choix d'hypothèses simplificatrices. La solution exacte tenant compte des amortissements a été fournie sans démonstration, afin de pouvoir définir les différentes constantes de temps (cf. chap. 6,7 et 8). La matière du volume X s'appuie sur les notions générales de l'électrotechnique (vol. I) et de l'électromécanique (vol. IX), sur certaines propriétés des matériaux (vol. II) et sur l'électromagnétisme en régime quasi-statique (vol. III). Elle fait appel égale- ment à des notions développées en électronique de puissance et de réglage (vol. XV et XVI) et en haute tension (vol. XXII).
