Book Description
LE TRAVAIL DE RECHERCHE RELATE DANS CE MEMOIRE CONSISTE A DEVELOPPER UNE METHODOLOGIE GENERALE D'ESTIMATION DES PARAMETRES PHYSIQUES DES MACHINES A COURANT ALTERNATIF, ET EN PARTICULIER DE LA MACHINE ASYNCHRONE DANS LE BUT DE REALISER SA MAINTENANCE PREVENTIVE EN EFFECTUANT LE SUIVI EN TEMPS REEL DE SON ETAT DE FONCTIONNEMENT. DANS UNE PREMIERE ETAPE LES DIFFERENTES METHODES D'ESTIMATION PARAMETRIQUE EXISTANTES ONT ETE RECENSEES AFIN D'ANALYSER LEURS PERFORMANCES RESPECTIVES. AINSI, UNE ETUDE THEORIQUE COMPARATIVE DU FILTRE DE KALMAN ETENDU ET DES METHODES A ERREUR DE SORTIE EN LIGNE A ETE MENEE. ELLE A PERMIS DE METTRE EN EVIDENCE LEUR PROFONDE ANALOGIE. CELLE-CI S'EST ENSUITE CONFIRMEE EXPERIMENTALEMENT LORS DE L'APPLICATION DE CES DEUX FAMILLES D'ALGORITHMES A L'IDENTIFICATION DU MODELE DE PARK DE LA MACHINE ASYNCHRONE. UNE VERSION HORS-LIGNE DU FILTRE DE KALMAN, REPOSANT SUR UN CRITERE QUADRATIQUE COMPOSITE PRENANT EN COMPTE L'INFORMATION A PRIORI DISPONIBLE SUR LE SYSTEME, EST EGALEMENT PROPOSEE. UNE STRATEGIE DE DIAGNOSTIC DE LA MACHINE ASYNCHRONE BASEE SUR LES ALGORITHMES A ERREUR DE SORTIE, EN LIGNE ET HORS-LIGNE, EST ENSUITE ELABOREE. CETTE STRATEGIE S'APPUIE A LA FOIS, SUR LE MODELE DE PARK ET SUR UNE ANALYSE FREQUENTIELLE DES RESIDUS D'ESTIMATION PARAMETRIQUE RESULTANTS POUR DETECTER ET DISCRIMINER UN DEFAUT STATOR D'UN DEFAUT ROTOR, ET SUR UN MODELE TRIPHASE DU STATOR POUR PERMETTRE LA LOCALISATION DU DEFAUT STATORIQUE. AFIN DE VALIDER EXPERIMENTALEMENT LA PROCEDURE DE DIAGNOSTIC AINSI DEFINIE, UN CERTAIN NOMBRE D'ESSAIS, EN SITUATION NORMALE DE FONCTIONNEMENT ET EN SITUATION DE DEFAUTS (COURT-CIRCUIT ENTRE SPIRES AU STATOR, RUPTURE DE BARRES AU ROTOR), SONT EXPLOITES. EN PARALLELE, UNE REFLEXION EST ENGAGEE POUR AFFINER LA MODELISATION PAR LA PRISE EN COMPTE DU PHENOMENE DE SATURATION FERROMAGNETIQUE ET DES PERTES DANS LE FER. L'ETUDE EXPERIMENTALE DE LA BOBINE A NOYAU DE FER, STRUCTURE DE BASE DES MACHINES ELECTRIQUES, A ALORS PERMIS DE VALIDER LE MODELE NON LINEAIRE DE SATURATION RETENU AINSI QUE LA METHODE D'IDENTIFICATION DEVELOPPEE.

Book Description
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 Description
This book reveals the French scientific contribution to the mathematical theory of nonlinear oscillations and its development. The work offers a critical examination of sources with a focus on the twentieth century, especially the period between the wars. Readers will see that, contrary to what is often written, France's role has been significant. Important contributions were made through both the work of French scholars from within diverse disciplines (mathematicians, physicists, engineers), and through the geographical crossroads that France provided to scientific communication at the time. This study includes an examination of the period before the First World War which is vital to understanding the work of the later period. By examining literature sources such as periodicals on the topic of electricity from that era, the author has unearthed a very important text by Henri Poincaré, dating from 1908. In this work Poincaré applied the concept of limit cycle (which he had introduced in 1882 through his own works) to study the stability of the oscillations of a device for radio engineering. The “discovery” of this text means that the classical perspective of the historiography of this mathematical theory must be modified. Credit was hitherto attributed to the Russian mathematician Andronov, from correspondence dating to 1929. In the newly discovered Poincaré text there appears to be a strong interaction between science and technology or, more precisely, between mathematical analysis and radio engineering. This feature is one of the main components of the process of developing the theory of nonlinear oscillations. Indeed it is a feature of many of the texts referred to in these chapters, as they trace the significant developments to which France contributed. Scholars in the fields of the history of mathematics and the history of science, and anyone with an interest in the philosophical underpinnings of science will find this a particularly engaging account of scientific discovery and scholarly communication from an era full of exciting developments.

Book Description
The purpose of this fantastically useful book is to lay out an overview on possible tools for state reconstruction in nonlinear systems. Here, basic observability notions and observer structures are recalled, together with ingredients for advanced designs on this basis. The problem of state reconstruction in dynamical systems, known as observer problem, is crucial for controlling or even merely monitoring processes. For linear systems, the theory has been well established for several years, so this book attempts to tackle the problem for non-linear systems.
