Public ISBD Titre : Implementation of artificial neural on an FPGA board application on induction motor speed control Type de document : texte imprimé Auteurs : Khalid Saadi, Auteur ; Anes Abderrahim Ouadria, Auteur ; Ammar Guellal, Directeur de thèse ; Larbes, Chérif, Directeur de thèse Editeur : [S.l.] : [s.n.] Année de publication : 2017 Importance : 80 f. Présentation : ill. Format : 30 cm. Accompagnement : 1 CD-ROM Note générale : Mémoire de Projet de Fin d'Etudes : Electronique : Alger, Ecole Nationale Polytechnique : 2017 Bibliogr. f. 79 - 80 Langues : Anglais (eng) Mots-clés : Artificial  neural  network  (ANN) FPGA C++  based  application Induction  motor Index. décimale : PN01217 Résumé : In many engineering applications, parallel distributed systems that satisfy the real-time constraint are strongly needed. Artificial neural networks (ANNs) represent highly parallel distributed systems that were directly inspired from the human brain. Thus they are appropriate for such applications. However the implementation of these networks proved to be quite challenging. It requires parallelism and flexibility. Among all types of circuits, FPGAs have proved to be the most convenient for that. But designing ANNs architectures to be implemented on FPGAs have some issues to be dealt with, like how to balance between numeric precision (required for accuracy), parallelism, and resources limitations. In this work we have proposed a C++ based application that generates optimized ANNs descriptions. We started first by introducing generalities on ANNs in chapter one. We devoted the second chapter to present an overview on the FPGA’s architecture. In chapter three we briefly presented the arithmetic issues in ANNs implementations. After that, we presented both architectures of a single neuron, and the whole ANN. we ended this chapter by presenting the way we coded our application and the principle of its functioning. ModelSim simulations where performed and they showed the good functioning of neural networks generated by the application. In the last chapter we have used our application to generate 6 ANNs that were used in a new induction motor control technique called ANN SHE. Simulations were performed as well and results were good and as expected.

Theoretical study on Selective Harmonics Elemination SHE PWM / Anes Abderrahim Ouadria 

Public ISBD Titre : Theoretical study on Selective Harmonics Elemination SHE PWM Type de document : texte imprimé Auteurs : Anes Abderrahim Ouadria, Auteur ; Larbes, Chérif, Directeur de thèse Editeur : [S.l.] : [s.n.] Année de publication : 2017 Importance : 30 f. Présentation : ill. Format : 30 cm. Accompagnement : 1 CD-ROM. Note générale : Mémoire de Master : Electronique : Alger, Ecole Nationale Polytechnique : 2017 Bibliogr. f. 30 Langues : Anglais (eng) Mots-clés : Motor  speed Inverter PWM Selective  Harmonic  Elimination  (SHE) Induction  motor Index. décimale : Ms14617 Résumé : Over the last years, many interests were given to the speed control of induction motor, thus so many researches has been made to develop technique and algorithm for a better control. The inverters were proved the best controller of these machines. They provide a PWM signal which is a succession of pulses, whose width is variable, and depends on the desired frequency spectrum. The calculated Pulse Width Modulation technique with Selective Harmonic Elimination and Voltage Control (SHE PWM) is an attractive alternative for speed control of an induction motor. This technique aim to calculate the switching angles, thus control the pulse width of the PWM signal to improve the efficiency of the motor and reduces the losses.
