At lower than rated loads, however, efficiency is greatly reduced. This letter describes using fuzzy logic to optimize the efficiency of an induction motor drive while keeping good dynamic response. The proposed fuzzy controller adjusts the magnetizing current component with respect to the torque current component to give the minimum total copper and iron losses.

One reason is the attraction of "newer" areas like computer engineering, which seem to excite the students more and pay higher starting salaries. In this difficult context, a significant educational investment is necessary to excite the students and entice them into Power Engineering. An area that students universally find interesting is alternate energy systems based on a renewable energy supply like wind. What is interesting with this area is that it includes the fundamental material that already exists in many energy conversion courses. Therefore, in this paper the authors present the development of a wind turbine prototyping software under Matlab/Simulink ® through undergraduate student projects within the Electrical and Computer Engineering Professional Institute (IUP GEII) at Amiens, France [1]. This software was developed by a group of three students of the Institute third and final year. It was then used by another group of three students of the Institute second year to realize a wind energy system model.

The proposed fuzzy approach is a sensor-based technique using the mains current measurement to detect intermittent loss of firing pulses in the inverter switches. A localization domain made with seven patterns is built with the stator Concordia current vector. One is dedicated to the healthy domain and the last six to each inverter switch. The fuzzy fault detector is designed on the basis of stator current analysis. Simulated experimental results on 1.5-kW induction motor drives show the feasibility of the proposed approach.

Using the fuzzy logic strategy, a better understanding of heuristics underlying the motor faults detection and diagnosis process can be achieved. The proposed fuzzy approach is based on the stator current Concordia patterns. Induction motor stator currents are measured, recorded, and used for Concordia patterns computation under different operating conditions, particularly for different load levels. Experimental results are presented in terms of accuracy in the detection motor faults and knowledge extraction feasibility. The preliminary results show that the proposed fuzzy approach can be used for accurate stator fault diagnosis if the input data are processed in an advantageous way, which is the case of the Concordia patterns.

This one allows generating the nonlinear VoltdHertz characteristic at low speed range in order to compensate the stator resistance effect. The comparative study between the ordinary Volts/Hertz control and designed Volts/Hertz fuzzy logic control shows clearly that the second one presents an increased of motor torque characteristics accompanied by a reduced machine losses without the stator resistance knowledge.

The proposed system adaptively reorganizes itself in the event of sensor loss or sensor recovery to sustain the best control performance given the complement of remaining sensors. Moreover, the developed system takes into account the controller transition smoothness in terms of speed and torque transients. For automotive application purposes two control techniques are chosen to illustrate the consistency of the proposed approach: sliding mode for encoderbased control and fuzzy logics for sensorless control. The system control reorganization is managed by a fuzzy decision system. Simulations tests, in term of speed and torque responses, have been carried out on a 4-kW induction motor drive to evaluate the consistency and the performance of the proposed fault-tolerant control approach.

Dans cet article, deux approches de commande tolérante aux défauts (FTC Fault-Tolerant Control) sont étudiées et appliquées à la machine asynchrone. Dans ce contexte, la phase de détection et d'isolation du défaut est décalée par rapport à la phase de reconfiguration de la commande. Celle-ci est réalisée en testant l'état d'un modèle interne qui s'active automatiquement dès l'apparition d'un défaut pour compenser son effet. Cet effet peut être convenablement modélisé par un signal exogène issu d'un système autonome stable appelé exosystème. Une commande additive est ainsi ajoutée à la commande nominale. Issue du modèle interne, cette commande sert à compenser l'effet du défaut. La première approche FTC exploite un modèle interne basé sur l'équation de Sylvester qui entraîne une divergence lorsque la machine est affectée par deux défaut ou plus. La seconde approche, quant à elle, élimine le problème de divergence par un réglage adapté des matrices du système.

The input variables of the fuzzy logic identifier are the input and output of the low-pass (LP) filter used to integrate the back-emf. Simulation results, using Matlab-Simulink, comparing the fuzzy estimator and a classical integrator in a direct torque control (DTC) scheme prove the superiority of the novel approach. The stator flux locus is smoothed and therefore torque ripples are reduced.

During the last 10 years, various original horizontal axis and vertical axis marine current turbines (MCT) have been developed around the world. Although various projects have been reported in the state-of-the-art research papers in recent years, many of these projects were only at the design stage when the papers were published. In fact, some projects do not have any further developments during the several years after the first reporting. In this paper, up-to-date information about large tidal turbine projects over 500 kW is focused. The newest achievements of these large tidal current turbine technologies are presented. These technologies represent the industrial solutions for several pre-commercial MCT farm projects in the coming years. This paper provides a useful background for researchers in the marine turbine energy domain.
