This book was released on 2010-08 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ce livre traite de la modélisation, la commande vectorielle et l'identification paramétrique de la machine asynchrone (à induction) triphasée. Une commande vectorielle de la machine asynchrone devient performante du moment où les paramètres du modèle mathématique sont connus. La modélisation doit prendre en compte les phénomènes de saturation magnétique et pelliculaires (ou de peau), et une validation des modèles doit se faire par superposition avec des essais réels. Avec les modèles conçus, nous procédons à l'étude de la commande vectorielle à flux rotorique orienté. Une analyse concernant la sensibilité des performances de commande face à la connaissance paramétrique de la machine étant le but principal. Des techniques de commande adaptative ont été abordées, tout en évitant l'identification en temps réel. Enfin, des méthodes d'identification paramétriques, déterministes et statistiques (maximum de vraisemblance) non linéaires, sont abordées. La validation des algorithmes conçus dans l'environnement MatLab / Simulink se fait par l'identification basée sur essais réels.
Download or read book Handbook of Asynchronous Machines with Variable Speed written by Hubert Razik and published by John Wiley & Sons. This book was released on 2013-01-24 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: This handbook deals with the asynchronous machine in its close environment. It was born from a reflection on this electromagnetic converter whose integration in industrial environments takes a wide part. Previously this type of motor operated at fixed speed, from now on it has been integrated more and more in processes at variable speed. For this reason it seemed useful, or necessary, to write a handbook on the various aspects from the motor in itself, via the control and while finishing by the diagnosis aspect. Indeed, an asynchronous motor is used nowadays in industry where variation speed and reliability are necessary. We must know permanently for the sensitive systems, the state of process and to inform the operator of the appearance of any anomaly and its severity.

Download or read book Electrical Actuators written by Bernard de Fornel and published by John Wiley & Sons. This book was released on 2013-03-04 with total page 366 pages. Available in PDF, EPUB and Kindle. Book excerpt: The different chapters of this book cover a large range of information regarding electrical actuators, including: synchronous and asynchronous machine modeling in order to measure and identify offline and online parameters using modern optimization methods; identification in real time of parameters with Luenberger filter and the extended Kalman filter; estimation of non-measurable variables, first by linear estimates and observers, then by lower observers. Robustness is a very problematic issue, as well, which is fully explored in a chapter dedicated to the subject. Finally, the estimate of non-measurable mechanical variables is particularly dealt with: estimate of load moment, then observation of the positioning of a command without mechanical sensor. The conditions to measure variables and real implementation of numerical algorithms are also examined with particular attention.
Download or read book Direct Eigen Control for Induction Machines and Synchronous Motors written by Jean Claude Alacoque and published by John Wiley & Sons. This book was released on 2012-10-09 with total page 270 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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). This totally new control method can be used not only for AC motor control but also to control input filter current and voltage of an inverter feeding an AC motor. Accessible and clear, describes a new fast type of motor control applied to induction machine (IM), surface mounted permanent magnet synchronous motor (SM-PMSM) and interior permanent magnet synchronous motor (I-PMSM) with various examples Summarizes a method that supersedes the two known direct control solutions – Direct Self Control and Direct Torque Control – to be used for AC motor control and to control input filter current and voltage of an inverter feeding an AC motor Presents comprehensive simulations that are easy for the reader to reproduce on a computer. A control program is hosted on a companion website This book is straight-forward with clear mathematical description. It presents simulations in a way that is easy to understand and to reproduce on a computer, whilst omitting details of practical hardware implementation of control, in order for the main theory to take focus. The book remains concise by leaving out description of sensorless controls for all motor types. The sections on “Control Process”, “Real Time Implementation” and “Kalman Filter Observer and Prediction” in the introductory chapters explain how to practically implement, in real time, the discretized control with all three types of AC motors. In order, this book describes induction machine, SMPM-SM, IPM-SM, and, application to LC filter limitations. The appendixes present: PWM vector calculations; transfer matrix calculation; transfer matrix inversion; Eigen state space vector calculation; and, transition and command matrix calculation. Essential reading for Researchers in the field of drive control; graduate and post-graduate students studying electric machines; electric engineers in the field of railways, electric cars, plane surface control, military applications. The approach is also valuable for Engineers in the field of machine tools, robots and rolling mills.
