Book excerpt: Dans de nombreuses applications (usinage, turbo-compression, transport, ...), les machines électriques à haute vitesse sont sollicitées pour améliorer les performances du système. Toutefois, elles cumulent des difficultés d’ordre électromagnétique, thermique et mécanique. Leurs matériaux doivent en effet offrir une bonne résistance aux forces centrifuges, ainsi qu’aux échauffements importants. Le travail présenté concerne principalement la modélisation analytique des pertes par courants induits dans les aimants des machines synchrones à aimants permanents déposés en surface. Deux méthodes originales sont proposées et comparées à des calculs par éléments finis 3D. Nous avons alors retenu la modélisation harmonique : la force magnétomotrice source est décomposée en série de Fourier dont la période est la largeur de l’aimant. La densité de courant induite dans l’aimant est alors déduite en résolvant un problème de magnétodynamique analogue à celui d’une couronne conductrice. Nous proposons ensuite une optimisation de machines à aimants en terre-rare afin de déterminer l’influence de ces pertes sur le dimensionnement optimal. En s’intéressant à la segmentation, nous avons montré que lorsque la largeur de l’aimant est inférieure au double de l’épaisseur de peau relative à un harmonique de rang suffisamment élevé, l’impact des pertes dans les aimants est relativement faible sur le dimensionnement.

Download or read book Computational Intelligence in Software Engineering written by Witold Pedrycz and published by World Scientific. This book was released on 1998 with total page 504 pages. Available in PDF, EPUB and Kindle. Book excerpt: This unique volume is the first publication on software engineering and computational intelligence (CI) viewed as a synergistic interplay of neurocomputing, granular computation (including fuzzy sets and rough sets), and evolutionary methods. It presents a unified view of CI in the context of software engineering. The book addresses a number of crucial issues: what is CI, what role does it play in software development, how are CI elements built into successive phases of the software life cycle, and what is the role played by CI in quantifying fundamental features of software artifacts? With contributions from leading researchers and practitioners, the book provides the reader with a wealth of new concepts and approaches, complete algorithms, in-depth case studies, and thought-provoking exercises. The topics coverage include neurocomputing, granular as well as evolutionary computing, object-oriented analysis and design in software engineering. There is also an extensive bibliography.
