▼ This study focuses on the development of novel model predictive control method for PMSM drive system. The aims of the proposed control method are flux and torque ripples reduction. The performances of the proposed model predictive control method and conventional direct torque control (DTC) are comparatively studied in both simulation and experimental tests. In recent years, various variable speed drive strategies and structures for PMSMs have been widely investigated and reported. Among these control strategies, the six-step control, field oriented control (FOC) and DTC are the most popular ones. Among them, the conventional DTC, which selects the desired voltage vector based on hysteresis comparators and switching table, features a fast dynamic response and very simple structure. The major demerits of DTC are large torque and flux ripples, variable switching frequency, and acoustic noises. Recently, the model based predictive control (MPC) was introduced to overcome these problems. However, the improvement was limited for the purposes of torque and flux ripple reduction and the MPC still suffered from variable switching frequency. The conventional DTC and MPC are similar in that they both select only one voltage vector per sampling period. This may result in overregulation, which is the key issue for torque and flux ripples and excessive acoustic noise. In this thesis, an improved MPC method with duty ratio optimization was proposed for PMSMs. The proposed method features low torque and flux ripples and relatively stable switching frequency. It is of most benefit when the drive system is working at a low sampling frequency because in the low frequency range, the proposed MPC drive system can achieve much lower torque and flux ripples than the original MPC and DTC, which is a very desirable feature for high power applications (e.g. electric vehicles). Finally, the numerical simulation and experimental test results of the conventional DTC, MPC, and improved MPC were presented to verify its effectiveness.

Afin de définir une conception optimale d’un système électromécanique, celui-ci doit intégrer des contraintes toujours plus drastiques et de nombreux phénomènes physiques issus de : l’électromagnétique, l’aérothermique, l’électronique, la mécanique et l’acoustique. L’originalité de cette thèse est de proposer une modélisation multi-physique pour la conception reposant sur des modèles à constantes localisées : solution intermédiaire entre la modélisation analytique et numérique. Ces différents modèles permettront l’étude et la conception sous contraintes d’une machine synchrone à aimants permanents dédiée pour la traction ferroviaire. Les résultats de simulations seront comparés à des résultats éléments finis mais aussi à des essais expérimentaux. Ce modèle multi-physique est entièrement paramétré afin d’être associé à des outils d’optimisation. On utilisera ici une optimisation par essaim de particules pour chercher des compromis entre différents objectifs sous forme de Front de Pareto. Dans ce papier, nous ciblerons les objectifs suivants : le couple d’origine électromagnétique et le bruit d’origine électromagnétique. Finalement une étude de sensibilité valide la robustesse de la conception retenue quand celle-ci est soumise aux contraintes de fabrication. L’objectif étant de poser les bases d’un outil d’aide à la décision pour le choix d’une machine électrique

In order to perform an optimal design of electromechanical system, the designer must take into account ever more stringent constraints and many physical phenomena from electric, magnetic, aeraulic, thermic, electronic, mechanic and acoustic. The originality of this thesis is to put forward a multi-physic design based on lumped models: halfway between analytical and numerical modeling. These models allow sizing a permanent magnet synchronous machine under constraints for rail traction. The results are validated with finite element simulations and experimental analysis. The multi-physic modeling is fully automated, parameterized, in order to combine the model with the optimization tool. We used here particle swarm optimization to search compromises between several objectives (Pareto Front). In this paper, we focus on electromagnetic torque and electromagnetic noise. Finally a sensitive study validates the robustness of selected design when it is subjected to manufacturing constraints. The aim of this work is to propose a decision tool to size electrical machines

▼ El empleo de motores eléctricos de tracción en diferentes aplicaciones industriales se está expandiendo debido a la gran versatilidad y robustez que presentan, y a los continuos progresos que se vienen realizando en el campo de la electrónica de potencia, y de la investigación en nuevos materiales. En el sector ferroviario, cada vez más se tiende a reducir el volumen requerido por los motores, y a que estos posean un alto grado de eficiencia energética. Además, se debe cumplir con las especificaciones de funcionamiento impuestas por el gerente de la infraestructura, así como las exigencias eléctricas y mecánicas impuestas por el constructor del vehículo ferroviario. Todo ello, conlleva a que los motores de tracción empleados estén operando bajo unas condiciones electromagnéticas y térmicas muy exigentes. Gracias a los avances que se han dado lugar en la última década en materia de computación, es posible generar e implementar diferentes modelos matemáticos que calculen correctamente las prestaciones de las máquinas, dando cuenta de los diferentes fenómenos electromagnéticos que se dan lugar debido a las exigencias de la aplicación. Las familias de motores de tracción ferroviaria que se estudian en esta tesis doctoral son los motores asíncronos, y síncronos con topología de rotor tanto de imanes superficiales como interiores. En esta tesis se define una metodología de dimensionamiento y cálculo para cada una de las familias de motores mencionadas. Dadas las condiciones de carga tan exigentes a las que operan este tipo de motores, se presentan diferentes modelos analíticos complejos que garanticen obtener correctamente las prestaciones de los motores. Además, se profundiza en el cálculo de pérdidas para lograr obtener correctamente la eficiencia del motor. Las diferentes metodologías presentadas, se han implementado en una herramienta analítica que permite diseñar motores de tracción que se adecúen de manera óptima a las exigencias. Empleando dicha herramienta, se describe el proceso de diseño de motores de las diferentes familias en base a unas especificaciones y restricciones para aplicación de tranvía, con dos objetivos: por un lado diseñar motores respetando el volumen establecido en las restricciones con el objetivo de maximizar el rendimiento; por otro lado, minimizar en lo posible el volumen de motor, manteniendo unos valores mínimos de rendimiento. Seguidamente se presentan diseños que cumplan con especificaciones para aplicación de metro, analizando la posibilidad de emplear diferente número de motores en función de la familia considerada. Finalmente se realiza una comparativa de los diseños realizados para las diferentes aplicaciones ferroviarias, presentando las ventajas existentes al emplear las diferentes familias de motores estudiadas en esta tesis.

Le transport routier est au cœur des enjeux environnementaux actuels. Les véhicules électriques hybrides (VEH) sont une alternative intéressante, notamment en milieu urbain. Cependant, la conception de tels systèmes est complexe car la chaîne de traction (composants et architecture), la mission et la gestion énergétique du véhicule sont intimement liées.Les travaux de V. Reinbold ont permis de mettre au point une méthodologie de dimensionnement de VEH. Les composants sont optimisés conjointement avec la gestion énergétique sur un cycle de fonctionnement afin de minimiser la consommation de carburant du véhicule. Une attention particulière est portée à la conception fine de la machine électrique via un modèle électromagnétique adapté à l’optimisation.Dans la suite de ces travaux, nous approfondissons plusieurs aspects du dimensionnement des VEH. Tout d’abord, nous introduisons la possibilité de gérer des paramètres discrets de la machine, comme le nombre de paires de pôles. Dans un second temps, nous développons un modèle thermique de la machine prenant notamment en compte les échanges autour des têtes de bobine. Ce modèle analytique par réseau de résistances thermiques est intégré puis utilisé dans le processus de dimensionnement par optimisation. Il a été préalablement validé via un modèle par éléments finis. Des méthodes d’analyse d’incertitude et de sensibilité sont appliquées afin de quantifier l’influence de certains paramètres thermiques. Enfin, nous appliquons la méthodologie de dimensionnement par optimisation à une architecture série/parallèle, intégrant deux machines électriques.

Road transportation has a huge impact on the environment. Hybrid electric vehicles (HEV) are an interesting alternative, especially for urban uses. However, HEV are complex systems to design because of the strong interaction between the component sizing, the energy management and the driving cycle.V. Reinbold previously developed a sizing methodology for HEV. The components and the energy management are simultaneously optimized to reduce the fuel consumption of the vehicle over a driving cycle. A specific electromagnetic model is used during the optimization process to describe accurately the electrical machine.As a continuation, we introduce firstly the possibility to deal with discrete variables such as the pole number of the electrical machine. Then, we develop a thermal model of the machine considering the convection exchanges around the end-windings. This analytical lumped parameter thermal network is used during the optimization process after being validated thanks to a finite element model. Uncertainty and sensitivity analysis are used to check the influence of some of the thermal parameters. Finally, the sizing methodology is applied to a series/parallel HEV including two electrical machines.

In this thesis, the basics of electromagnetic theory for wave-energy conversion are reviewed, some of the characteristics of the ocean wave are investigated, some of the power take-off (PTO) systems are introduced, and details about linear permanent magnetic machines, in particular, are discussed. The thesis aims to model the novel linear transverse flux machine designed by Anders Hagnestål and to build hysteresis current controller for power factor correc- tion. Although this machine is expected to have high performance in terms of efficiency, it also exhibits a strong mutual interaction between the three phases of the machine. Thus, simplification of the actual model of the machine is im- posed to mitigate the complexity of the machine and facilitate the Simulink model. Four cases of the double band hysteresis control are studied. The cur- rents seem to be responding properly to the control scheme; however, software and hardware programming of a microprocessor would be preferable to ensurethe applicability of the control strategy in a real environment.

I detta examensarbete undersöks elektromagnetisk teori och havsvågors egenskaper. Några energiomvandlingssystem introduceras och permanentmagnetiserade maskiner diskuteras i detalj. Syftet med avhandlingen är att modelleraen ny linjär transversalflödesmaskin som är designad av Anders Hagnestål och att bygga en hysteresbaserad strömkontroll för denna. Även om maskinen förväntas prestera bra, uppvisar den också en stark ömsesidig magnetisk interaktion mellan de tre faserna. För att kunna hantera detta problem och därmed kunna genomföra simuleringar införs en förenklad elektromagnetisk modell av maskinen. En strömkontroller har implementerats i Simulink, där fyra fall av dubbelbandshystereskontroll studerats. Resultaten från simuleringarna visar att strömkontrollern fungerar. Nästa steg i projektet är att utföra mjukvaru och hårdvaruprogrammering av en mikrokontroller för att testa systemet i enverklig miljö.

▼ Thermal modelling is of great importance in all electric machines but especially in permanent magnet synchronous machines (PMSMs). The thermally fragile permanent magnets (PMs) can more easily be demagnetized at high temperatures. When high speed machines are considered, heat extraction surfaces are small due to the higher energy density. This thesis focuses on the thermal modelling of a high speed slotless PMSM using analytical techniques. From literature it is clear that analytical distributed models have not reached its full potential in thermal modelling of electric machines. Thermal experiments on high speed electric machine, including rotor PM temperature measurements are not commonly found in literature. The thermal behaviour of each component of the machine is influenced by the overall temperature distribution. The widely used lumped parameter (LP) cylindrical component model derived by Mellor et al. is used to derive a LP model of the entire machine. A two dimensional (2-D) analytical distributed model is derived for the rotor PM using the separation of variables method. Three of the boundaries are assumed to be of the convection type and the fourth of constant heat flow type. Different convection coefficients are assumed to exist in the radial and axial directions. The distributed model is verified using COMSOL R and good correlation is shown. The distributed model is used to determine the temperature distribution in the PM and the convection heat flow in the axial direction. Loss calculation is an integral part of thermal modelling. Temperature changes in an electric machine is due to the interaction between the heat generation (losses) and heat removal. The losses found in a high speed slotless PMSM are investigated. A 2-D analytical magnetic model is used to determine the stator lamination loss as well as the stator winding eddy current loss. A simple LP model is derived for the rotor eddy current loss. Due to the relatively large resistivity of the shielding cylinder and PM material, the rotor eddy current loss is a significant part of the total machine loss. The tangential current width is determined empirically in this thesis but a 3-D distributed model which includes end space effects and skin depth could also be used. A large part of thermal modelling is empirically based. The convection and interface resistances are determined through a set of experiments in this thesis. The measured and calculated convection coefficients correlated well for both forced and natural convection cooling. A large temperature increase found during the no-load test can be attributed to large bearing loss, possibly due to axial loading. The LP model is modified to include the phenomena found during the experiments. The thermal model is used to predict the temperatures of a high speed PMSM at rated load and speed. Although the PM is not heated above the Curie temperature, demagnetization is still possible. According to the model, the machine will not be able to operate at full load and …

▼ This thesis investigates the dynamic control performances of a 14-pole/18-slot fractional slot concentrated winding (FSCW) interior permanent magnet synchronous machine (FSCW IPMSM). The machine was run with two commonly used control techniques: Field Oriented Control (FOC) and Direct Torque and Flux Control (DTFC). The FSCW IPMSM under consideration was previously designed and constructed at the University of New South Wales (UNSW) to achieve a high torque/high power density, high efficiency, a very wide (> 10:1) constant power speed range and very low cogging torque. The key favourable characteristic of an FSCW is the short end windings, which results in low copper loss and more compact design compared to its distributed winding counterpart. The other benefit of this particular 14-pole/18-slot FSCW IPMSM design includes some saliency ratio, which is desirable for sensorless control, compared to other CW permanent magnet machines. Nevertheless, this type of machine has so far been only investigated in terms of steady state performance; the dynamic control performance has not been studied yet. The major objective of this study is to investigate the dynamic control performances of the 14/18 FSCW IPMSM machine while running with model based controllers such as the FOC and DTFC, to study their limitations and to propose improvements of these controllers.The FOC was first implemented in the prototype FSCW machine using standard distributed windings IPMSM mathematical model. A number of issues associated with the FSCW IPMSM under FOC were detected and investigated thoroughly. The issues were resolved by implementing a closed-loop rotor position compensator and a new voltage compensation scheme.It is believed that this thesis, for the first time, applied the Sensorless Direct Torque and Flux Control (DTFC) to a FSCW IPMSM. The performances of the FSCW-IPMSM under DTFC at very low speed, however, were not satisfactory. To improve the performance of the DTFC at low speed operation, a closed-loop extended flux linkage model is proposed. Although it was proven that the proposed closed-loop extended flux linkage DTFC is superior to the open-loop DTFC, the extremely low speed operation still is not achieved. To elevate the performance of the sensorless DTFC drive in extremely low speed religion, including standstill, a sensorless DTFC based on high frequency injection method for the FSCW IPMSM is implemented in this thesis.

▼ The performance capability of a four pole Synchronous Reluctance Machine (SynRM) is improved using an optimized coordinate based four flux barrier hyperbolic rotor structure. Firstly, a study is conducted to compare and improve the operating performance of 36 slot four-pole SynRMs optimally designed based on three distinct Objective Functions (OFs) for (i) torque ripple minimization (RM), (ii) saliency ratio maximization (SM), and (iii) combined objective function (COF) optimization to simultaneously minimize the torque ripple and maximize the saliency ratio while supporting the required torque. For the optimized SynRMs, a normal round rotor and a rotor with a cut-off are used in the Finite Element (FE)-based rotor design optimization, while the stators are identically designed using classical electric and magnetic loading principles. The SynRMs’ dimensions and efficiencies are based on IEC-90S frame size limitations and IE3 efficiency standards, respectively. Secondly, two additional SynRMs with 24 slots and 48 slots are considered with normal and cut-off rotors. Four new SynRMs are optimized using appropriate COFs to minimize the torque ripple and maximize the saliency ratio of the machines while also supporting the desired developed torque. Performance of each optimized SynRM is compared to introduce a final design. Finally to further improve performance capabilities such as developed torque, power factor and wide speed range, addition of low-cost ferrite magnet is considered along q-axis. A different COF is used to maximize the developed torque and reduce torque ripple simultaneously for the design optimization of PM assisted SynRMs (PMaSynRMs). A comparative electromagnetic study and mechanical stress and deformation analysis are carried out to predict the performance capabilities and operating limits of the designed SynRM and PMaSynRMs. The optimally designed SynRM and PMaSynRM are fabricated and tested to verify the theoretical expectations.

A teoria de duplo eixo é geralmente utilizada para modelar e caracterizar máquinas síncronas de polos salientes. O conhecimento das indutâncias de eixo direto e eixo em quadratura são fundamentais para o desenvolvimento destes modelos e para o projeto de controladores destas máquinas. No entanto, métodos tradicionais para determinação destas indutâncias através de ensaios tornam-se impraticáveis em máquinas síncronas de ímãs permanentes pela impossibilidade de controlar a corrente de campo. Recentemente, a IEEE publicou o Std. 1812, chamado Trial-Use Guide for Testing Permanent Magnet Machines, que pode servir de guia para obtenção da reatância de eixo direto Xd. Esta norma não sugere formas de determinar a reatância de eixo em quadratura Xq, mas existem diferentes métodos para calcular este parâmetro a partir de dados coletados em testes, geralmente envolvendo medição de ângulo de carga. O objetivo deste trabalho é propor e analisar dois métodos alternativos para determinar as reatâncias do modelo de duplo eixo através de ensaios aplicados a um gerador síncrono de ímãs permanentes (GSIP) de 1,5 kW. O primeiro é baseado em predição de ângulo de carga e o segundo é baseado em medição de ângulo de carga. O primeiro combina ensaios a vazio e de curto circuito com análise do diagrama fasorial para descrever o ângulo de carga como função de grandezas elétricas facilmente mensuráveis. O segundo propõe um método de medição de ângulo de carga com auxílio de um encoder incremental. Resultados comprovam que é possível determinar indutâncias do modelo de duplo eixo com as equações desenvolvidas desde que o conteúdo harmônico não seja elevado.

▼ Many critical five-phase permanent magnet synchronous machine (PMSM) drive systems require operation after either a single or dual open-phase fault occurs. Some of these drive systems use the open-end winding inverter topology as it allows for the injection of unbalanced phase currents, i.e. currents that do not sum to zero. This allows for better optimization of the machine torque after open-phase faults occur. The post-fault phase currents are often controlled using the field-oriented control (FOC) technique. However, all previously proposed FOC transformations yield non-dc references when controlling unbalanced phase currents. Therefore, these techniques will experience tracking errors, with the PI current controllers, that create undesired distortions in the phase currents.This thesis focuses on proposing post-fault FOC transformations that yield dc references when controlling multiple sets of unbalanced phase currents. These sets of currents include three unbalanced sinusoidal phase currents, four unbalanced sinusoidal phase currents and three unbalanced phase currents with fundamental and third harmonic components. These current sets are for different post-fault optimization approaches in the event of a single or dual open-phase fault in a five-phase PMSM system. The proposed techniques are significant in that they do not suffer from tracking errors, like the previous FOC transformations, when controlling these currents. Example FOC transformations are developed for each case and are used to experimentally demonstrate, using a specialized experimental testbed, that these transformations can be used in an FOC architecture to accurately control the post-fault phase currents with zero tracking error.This thesis also proposes a generalized post-fault optimization algorithm for the event of an open-phase fault in a multi-phase PMSM system. This technique includes any desired constraints on the current form whilst determining the optimal phase currents which yield the desired torque waveform. Also, a new modulation method is proposed which accurately generates the zero-sequence voltage reference when operating in the over-modulation region. This avoids obtaining high current distortion when operating in the over-modulation region with the five-phase open-end winding configuration. The work performed in this thesis is significant to the field of post-fault control of multi-phase PMSMs and the control of the open-end winding inverter topology.

▼ With the advent of high power density motors in applications such as electric vehicles, the need for an effective thermal analysis of motors is further warranted to ensure their efficient and reliable operation. While existing Lumped Parameter Thermal Models (LPTMs) provide a convenient method for the thermal evaluation of motor designs, they provide a single, average temperature of the various regions of the motor without data on the temperature variation in the axial direction. LPTMs are a convenient reduced finite-element method to analyze the thermal performance of electric motors based on their design parameters and operating conditions. In this thesis the thermal analysis of a Permanent Magnet Assisted Synchronous Reluctance Motor (PMa-SynRM) is conducted by proposing two LPTMs: 1. Radial Lumped Parameter Thermal Model (R-LPTM).2. Axial Lumped Parameter Thermal Model (A-LPTM).The R-LPTM adopts an existing approach considered for the thermal modeling of interior rotor configurations with the key contribution being the modeling of the unique rotor configuration of the PMa-SynRM under study. In this approach, the individual geometries of the motor are modeled as single nodes, the voltages of which correspond to the average temperature for the respective machine part. The A-LPTM introduces a novel thermal model by employing the Finite Volume Method (FVM). While the R-LPTM models heat flow only in the radial direction due to the lamination structure of the stator and the rotor regions, the extension of this approach to the axially thermally shorted conductor coil sides, the magnets and the shaft results in a relative oversimplication of the heat transfer in these regions. While equivalent lumped thermal resistances model axial heat flow in these regions in the R-LPTM, by employing the FVM in the A-LPTM a higher resolution of axial temperature data is determined by providing a more accurate method of radial and axial heat flow modeling in these regions. In this model, the conductors, magnet and shaft nodes are evaluated as a function of the position along the axial length of the machine to determine their corresponding axial temperature variation.The results of both the thermal models formed in this thesis have been evaluated and the results were compared with both experimental and Finite Element Analysis (FEA) data. The experimental data was determined using temperature sensors mounted at various points in the machine. For the temperature measurement of the magnet an innovative Printed Circuit Board (PCB) integrated with sensors and wireless data transmission capabilities was mounted on the rotor for real time axial temperature measurement of the magnets.An analysis comparing the data from the R-LPTM and the A-LPTM shows the advantages of the A-LPTM. Additionally, plots of the accuracy of data obtained from both the models clearly highlights their respective accuracy when compared to the experimentally measured values. Lastly, a sensitivity analysis of both models was determined as a function of the thermal… Advisors/Committee Members: Choi, Seungdeog (Advisor).

Cette thèse présente le dimensionnement d’une machine électrique à rotor disque pour la traction de véhicules hybrides. Un état de l’art complet sur les machines électriques à rotor disque permet de montrer que la machine à flux axial à rotor central est la plus adaptée. Différentes géométries du circuit magnétique sont successivement étudiées et comparées par simulations par éléments finis. Pour maximiser le rendement de la machine, les pertes d’origine électromagnétique sont étudiées. Un modèle analytique des pertes par effet de peau dans les conducteurs de cuivre est proposé et validé par éléments finis. Un second modèle analytique estime les pertes par courant induits dans les aimants permanents pour tous les points de travail de la machine se basant sur uniquement trois simulations par éléments finis permettant ainsi un gain de temps important lors du dimensionnement. Deux méthodes de dimensionnement sont comparées : le dimensionnement manuel par essais/erreurs et l’optimisation multi-objectifs. Cette dernière méthode automatise le dimensionnement et permet une optimisation plus pointue et une forte amélioration des performances. Dans ce cas, la densité de couple a par exemple été augmentée de 29%. La machine à flux axial dimensionnée est comparée avec une machine à flux radial pour véhicules hybrides. Cette comparaison révèle le potentiel de la machine à flux axial avec notamment une densité de couple augmentée de plus de 20%. Enfin, deux prototypes ont été construits et mesurés pour valider les simulations.

This PhD presents the design of a disc rotor electric machine for the traction of hybrid vehicles. A complete state of the art enables the selection of the internal rotor axial flux machine which is the most suited to this application. Different geometries of the magnetic circuit are successively studied and compared with finite elements simulations. To maximize the efficiency of the machine losses generated in the magnetic circuit are studied. An analytic model on the skin effect in the copper conductors is proposed and validated with finite elements simulations. A second analytic model estimates the eddy current losses in the permanent magnets for every operating point of the machine based on only three finite element simulations enabling an important time-saving. Two dimensioning methods are compared: the manual dimensioning based on a tries/errors method and the multi-objectives optimization. This last method automates the dimensioning and enables a more refined optimization and a strong improvement of the performances. For example, the torque density has been improved by 29% in that case. The designed axial flux machine is compared to a state of the art radial flux machine for hybrid vehicle. This comparison shows the potential of the axial flux machine with an improvement of the torque density by more than 20%. Finally two prototypes have been built and measured to validate the simulations.

O presente trabalho trata do estudo e análise da influência da saturação magnética no torque de uma máquina síncrona com ímã permanente no rotor. A máquina síncrona em es-tudo trata-se de uma máquina cuja forma de onda de força contra eletromotriz é trapezoidal. Inicialmente é feito um estudo sobre os efeitos da saturação magnética nos três principais parâmetros da máquina, indutância de fase, relutância (vista pelo circuito que tem como fonte de fluxo magnético os ímãs permanentes) e a força contra eletromotriz. Em seguida, realiza-se um estudo sobre o torque eletromagnético para a máquina e a importância dos parâmetros estudados, demonstrando a forte dependência da qualidade do torque com estes parâmetros. Com base nos estudos sobre saturação e torque, objetiva-se, portanto, descrever o comportamento de cada um dos parâmetros quando da saturação da máquina e quanto/como cada um deles afeta o torque eletromagnético da máquina. A fim de se estudar cada componente do torque separadamente, avalia-se a máquina por meio do Método da Permeabilidade Fixa. Por fim, faz-se simulações em elementos finitos empregando o método apresentado e os resultados são analisados.

This work deals with the influence of magnetic saturation on torque of permanent mag-net synchronous machine. At first, a study of magnetic saturation is carried out in order to understand its influence on three main machines parameters, phase inductance, magnet re-luctance and back electromotive force. A study describing the electric torque and its compo-nents is carried out. This study explain the importance of each machines parameter on electric torques smoothness and amplitude. In order to investigate and describe each torques com-ponent, a review on Frozen Permeability Method is developed. At last, some simulation by means of finite element method with Frozen Permeability Method are carried out. The results are shown and analyzed.

Durant ces dernières décennies, le moteur synchrone à aimants permanents (MSAP) est devenu un actionneur essentiel pour les applications militaires, industrielles et civilesgrâce à ses avantages de haute densité de puissance, de rendement élevé, de grande fiabilité avec une structure simple, un faible volume et un poids réduit. Parfois, plusieurs MSAP sont utilisés pour effectuer des tâches coopératives. Par exemple le boggie d'une locomotive ou encore les surfacesde vol d'un avion. Ces MSAP fonctionnent généralement à la même vitesse. Pour réduire le volume et le poids, une idée de mutualisation des dispositifs de conversion statique, appelée système Multi-MSAP Mono-Convertisseur (MIMSAPMC), est proposée. Bien que de nombreux chercheurs aient déjà proposé différentes solutions de contrôle pour le système MIMSAPMC, la plupart d'entre eux ne garantissent pas la stabilité et l'efficacité énergétique du système. Ceci estdevenu le plus grand obstacle à l'utilisation pratique du MIMSAPMC. A cet effet et en commençant par un système MIMSAPMC avec 2 moteurs nous avons testé expérimentalement quelques stratégies de commande pour en vérifier la faisabilité et les performances. Sur la base des données mesurées, nous avons constaté que le problème de sur-contraintes existe dans certaines stratégies de contrôle. Ensuite, la synthèse d’une commande basée sur un modèle en régime permanent d'un système MIMSAPMC est réalisée. En étudiant le problème d'existence du régime permanent, nous formulons une procédure de conception de la structure de la loi de commande. En combinant la stabilité en boucle ouverte et la solution en régime permanent, nous définissons alors la région de contrôlabilité et de stabilité. La méthode des multiplieurs de Lagrange est ensuite utilisée pour formuler l'expression de l'état d'équilibre optimal en fonction ducouple et de la vitesse. L'expérience a montré que l'efficacité avec cette nouvelle loi de commande s’est considérablement améliorée. Dans le même temps, nous avons exploré l'influence de la variation des paramètres pour la stabilité du système et pour l'optimisation de l'efficacité. Ainsi, nous montrons que la variation paramétrique influence la zone de stabilité. Mais son influence peut être éliminée en utilisant la stratégie Maitre-Esclave. Par ailleurs, en ce qui concerne l'optimisation de l'efficacité énergétique, les résultats de simulation ont montré que la non-concordance des paramètres, en particulier le flux de l’aimant, peut entraîner une perte d'efficacité élevée. Dans la dernière étape, ce contrôleur est également adapté à un système MIMSAPMC avec un nombre de moteurs supérieurs à 2. Les résultats de la simulation démontrent alors l'efficacité de la proposition.

During these decades, Permanent Magnet Synchronous Motor (PMSM) has become a vital part of military, industry and civil applications due to the advantages of high power density, high efficiency, high reliability and simple structure, small volume and light weight. Sometimes, multiple PMSMs are used to carry out cooperative…

Dans le cadre de la réduction des émissions des gaz à effet de serre, et devant l'augmentation incessante du prix de l'énergie, la course à l'amélioration des performances énergétiques touche tous les secteurs : industriel, tertiaire ou même celui des particuliers. La consommation de l'énergie électrique est due en grande partie aux moteurs électriques, et particulièrement les machines asynchrones, utilisées dans diverses applications telles que le pompage, la ventilation ou la compression. Ces machines sont caractérisées par des rendements relativement faibles et leur remplacement par des machines plus performantes permettrait un gain d'énergie non négligeable. Les machines à aimants permanent ayant pouvoir de démarrage autonome sont de bonnes candidates pour répondre à ce besoin. Elles ont de très bons rendements et les artifices supplémentaires permettant le démarreur automne suppriment la nécessité d'utiliser des convertisseurs statiques comme dans le cas des machines à aimants classiques. Des contraintes spécifiques se posent cependant pour l'utilisation et le dimensionnement de ces machines : en effet, le courant de démarrage ne doit pas être trop important à cause du risque de démagnétiser les aimants et le couple de démarrage doit être suffisamment grand pour assurer un démarrage en charge. Par ailleurs les rendement et facteurs de puissance en pleine charge doivent être assez nettement supérieurs à ceux des machines asynchrones pour les rendre plus compétitives. Dans cette thèse, nous étudions trois structures de rotor permettant de répondre à un cahier des charges donné. Ces trois structures utilisent des aimants en surface, insérés dans un rotor massif ou dans un rotor à cage. Elles ont leurs avantages et leurs inconvénients, que nous avons mis en évidence par une étude comparative assez détaillée. Cette étude comparative n'a pu être mise en oeuvre sans l'établissement de modèles en régime statique ou dynamique de ces machines ou encore de méthodologie de conception. Un prototype à échelle réduite a été dimensionné, réalisé et testé au laboratoire ; il confirme les principes de base de ce type de machines

In the context of reducing emissions of greenhouse effect, and of energy cost, the competition to improve the performances of the equipments affects all the domains. The consumption of electricity is mostly due to the electric motors, and particularly induction machines, used in various devices such as pumps, fans or compressors. These machines are characterized by relatively low efficiencies, and their replacement by more efficient machines should lead to a significant power saving. The Line-Start Permanent Magnet motors are good candidates to achieve this purpose. They have higher efficiencies and the additional devices for self-start eliminates the need of static converters, as it is normally required for conventional permanent magnet motors. Specific constraints arise for the use and the design of these machines: the starting current should not be so high to avoid the risk of the demagnetization of…
