Book Synopsis Electrical Machines Diagnosis by : Jean-Claude Trigeassou
Download or read book Electrical Machines Diagnosis written by Jean-Claude Trigeassou and published by John Wiley & Sons. This book was released on 2013-02-07 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: Monitoring and diagnosis of electrical machine faults is a scientific and economic issue which is motivated by objectives for reliability and serviceability in electrical drives. This book provides a survey of the techniques used to detect the faults occurring in electrical drives: electrical, thermal and mechanical faults of the electrical machine, faults of the static converter and faults of the energy storage unit. Diagnosis of faults occurring in electrical drives is an essential part of a global monitoring system used to improve reliability and serviceability. This diagnosis is performed with a large variety of techniques: parameter estimation, state observation, Kalman filtering, spectral analysis, neural networks, fuzzy logic, artificial intelligence, etc. Particular emphasis in this book is put on the modeling of the electrical machine in faulty situations. Electrical Machines Diagnosis presents original results obtained mainly by French researchers in different domains. It will be useful as a guideline for the conception of more robust electrical machines and indeed for engineers who have to monitor and maintain electrical drives. As the monitoring and diagnosis of electrical machines is still an open domain, this book will also be very useful to researchers.
Book Synopsis Diagnostic des systèmes non linéaires by : Cédric Join
Download or read book Diagnostic des systèmes non linéaires written by Cédric Join and published by . This book was released on 2002 with total page 177 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ce mémoire porte sur le diagnostic de systèmes non linéaires. Dans le but de déterminer le type et l'apparition de défauts, des résidus structurés sont générés en respectant les étapes suivantes : la première étape est le découplage d'une partie de l'état du système de l'effet des perturbations à l'aide d'une méthode qui permet de diminuer la dimension du sous-espace d'état sensible à la perturbation ; la seconde étape est l'étude des sous-espaces d'état sensibles aux défauts dans le but de proposer une alternative au FPRG ; la troisième étape est la synthèse de filtres d'isolation des défauts qui intègre une étude de la convergence des estimations de l'état du filtre vers l'état réel du système. Des simulations d'un système hydraulique mettent en relief l'apport des méthodes proposées. Un formalisme algébrique du diagnostic pour les systèmes linéaires qui semble être une perspective intéressante pour les systèmes non linéaires est proposé.

Condition monitoring of machines in non-stationary operations is the title of the presented book and the title of the Conference held in Hammamet - Tunisia March 26 – 28, 2012. It is the second conference under this title, first took place in Wroclaw - Poland , March 2011. The subject CMMNO comes directly from industry needs and observation of real objects. Most monitored and diagnosed objects used in industry works in non-stationary operations condition. The non-stationary operations come from fulfillment of machinery tasks, for which they are designed for. All machinery used in different kind of mines, transport systems, vehicles like: cars, buses etc, helicopters, ships and battleships and so on work in non-stationary operations. The papers included in the book are shaped by the organizing board of the conference and authors of the papers. The papers are divided into five sections, namely: Condition monitoring of machines in non-stationary operations Modeling of dynamics and fault in systems Signal processing and Pattern recognition Monitoring and diagnostic systems Noise and vibration of machines The presented book gives the back ground to the main objective of the CMMNO 2012 conference that is to bring together scientific community to discuss the major advances in the field of machinery condition monitoring in non-stationary conditions.
Book Synopsis A diagnostic model framework for water use in rice-based irrigation systems by : Wilfried Hundertmark
Download or read book A diagnostic model framework for water use in rice-based irrigation systems written by Wilfried Hundertmark and published by IWMI. This book was released on 2003 with total page 57 pages. Available in PDF, EPUB and Kindle. Book excerpt: The paper presents a framework for water use in rice-based irrigation systems, which is based on linear programming (LP). This framework intends to facilitate improved understanding of a system's internal and external conditions and the constraints to productive use of the available land and water resources, and thereby create a reference for the assessment of the physical, economic and environmental performance of a given system. The framework is conceived as a tool that is used interactively in technical group sessions with farmers, system operators and extension workers, where structured discussions lead to improved data confidence, and understanding of complex irrigation systems.

Book Synopsis Multimodèles en automatique by : CHADLI Mohammed
Download or read book Multimodèles en automatique written by CHADLI Mohammed and published by Lavoisier. This book was released on 2012-06-01 with total page 194 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pour représenter au mieux le fonctionnement dynamique d'un processus, une approche globale basée sur de multiples modèles LTI (linéaires ou affines) autour de différents points de fonctionnement est utilisée. Cette approche multimodèle est une représentation polytopique convexe pouvant être obtenue, soit directement à partir d'un modèle mathématique non linéaire, soit par transformation mathématique, soit par linéarisation autour de différents points de fonctionnement. Basé essentiellement sur la deuxième méthode de Lyapunov et la formulation LMI, Multimodèles en automatique se concentre sur l'analyse de la stabilité et la synthèse de correcteurs/observateurs. Le cas des multimodèles incertains avec des entrées inconnues est étudié et les fonctions de Lyapunov quadratiques et non quadratiques sont également considérées. Afin de réduire le pessimisme de la méthode quadratique, l'étude de stabilité des multimodèles est réalisée en considérant des fonctions de Lyapunov non quadratiques.

This book was released on 2007-03-01 with total page 1576 pages. Available in PDF, EPUB and Kindle. Book excerpt: The safe and reliable operation of technical systems is of great significance for the protection of human life and health, the environment, and of the vested economic value. The correct functioning of those systems has a profound impact also on production cost and product quality. The early detection of faults is critical in avoiding performance degradation and damage to the machinery or human life. Accurate diagnosis then helps to make the right decisions on emergency actions and repairs. Fault detection and diagnosis (FDD) has developed into a major area of research, at the intersection of systems and control engineering, artificial intelligence, applied mathematics and statistics, and such application fields as chemical, electrical, mechanical and aerospace engineering. IFAC has recognized the significance of FDD by launching a triennial symposium series dedicated to the subject. The SAFEPROCESS Symposium is organized every three years since the first symposium held in Baden-Baden in 1991. SAFEPROCESS 2006, the 6th IFAC Symposium on Fault Detection, Supervision and Safety of Technical Processes was held in Beijing, PR China. The program included three plenary papers, two semi-plenary papers, two industrial talks by internationally recognized experts and 258 regular papers, which have been selected out of a total of 387 regular and invited papers submitted. * Discusses the developments and future challenges in all aspects of fault diagnosis and fault tolerant control * 8 invited and 36 contributed sessions included with a special session on the demonstration of process monitoring and diagnostic software tools

Book Synopsis Transport, Chaos And Plasma Physics 2 by : Benkadda Sadruddin
Download or read book Transport, Chaos And Plasma Physics 2 written by Benkadda Sadruddin and published by World Scientific. This book was released on 1996-08-22 with total page 460 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the early developments of 'nonlinear science', plasma physics played a major role in its evolution: solitons, hamiltonian chaos, distinction between absolute and convective instabilities, and dynamics of coherent structures in turbulence. Understanding transport in plasmas is important for fusion devices but also for fundamental astrophysics, for fluid mechanics, for theoretical chemistry and engineering, and plasma processing in engineering.This second workshop gathered experts in plasma physics, nonlinear phenomena and mathematics. It aimed at enabling theoreticians, numericians and experimentalists in plasma turbulence to relate electromagnetic fluctuations, modes of self-organisation and transport processes. It may lead to developing new diagnostics and new methods for signal processing.
Book Synopsis Classic Papers in Modern Diagnostic Radiology by : Adrian M.K. Thomas
Download or read book Classic Papers in Modern Diagnostic Radiology written by Adrian M.K. Thomas and published by Springer Science & Business Media. This book was released on 2005-09-02 with total page 683 pages. Available in PDF, EPUB and Kindle. Book excerpt: I am very pleased to have been asked to write the foreword to this book. The technical advances in diagnostic radiology in the last few decades have transformed clinical practice and have been nothing short of astonishing. The subject of diagnostic radiology is now very large and radiology depa- ments are involved in all areas of modern patient care.The defining event in m- ern radiology,and arguably the most significant development in radiology since Wilhelm Röntgen discovered X-rays, was the invention of the CT scanner in the 1970s.The CT scanner introduced modern cross-sectional imaging and also di- tal imaging.We now have MRI and ultrasound and these techniques are replacing many traditional X-ray procedures.The developments in radiology have been the result of a fruitful interaction between the basic sciences, clinical medicine and the manufacturers. This can be seen by looking at the various sources of these publications. Change is produced by the interactions between the various dis- plines. The editors have had a very difficult task in selecting the key discoveries and descriptions.The radiological literature is very large.Medical imaging continues to develop rapidly and these papers are the foundations of our current practice.
