Le premier chapitre expose le phénomène, fait une synthèse des relations mécaniques et acoustiques existantes et les confronte avec des expériences pratiques.
Une méthode de calcul des harmoniques d'induction présents dans l'entrefer est développée dans le deuxième chapitre, ils sont responsables des forces de Maxwell à l'origine du bruit. Les relations obtenues sont valables pour un moteur à rotor bobiné ou à cage et permettent la détermination des harmoniques de courant rotorique et statorique. Elles sont comparées à celles données par d'autres auteurs qui négligent certains termes.
Les applications numériques présentées dans le troisième chapitre soulignent l'importance d'un phénomène qualifié de résonance de denture, responsable de courants rotoriques harmoniques importants et de bruit magnétique. Elles montrent également la validité de la théorie en comparant les résultats aux relevés pratiques.
Le dernier chapitre expose le principe de réduction active du bruit magnétique. Il consiste à injecter un faible courant harmonique créant une force qui s'oppose à celle à l'origine du bruit. Plusieurs montages sont proposés, permettant l'injection d'un courant supplémentaire dans une machine alimentée par le réseau. L'étude expérimentale permet de valider le procédé.

This work takes place in the context of the development of powertrains for electric vehicles. Those developments have raised new issues such as noise and vibrations of electrical machines, which are important issues in automotive applications. The aim of this thesis is to develop control laws dedicated to the reduction of currents harmonics that are responsible for vibration harmonics.In that purpose, different parts of the system have been modelled. Parameters of the electrical model of the studied machine have then been identified thanks to experimental measurements.Two different control laws are proposed and developed. One the one hand, a controller is synthetized thanks to H-infinity optimization. On the other hand, the studied current harmonic is modelled as coming from an external disturbance. This virtual disturbance is estimated thanks to an observer and compensated

This research aims at solving a particular vibration control problem of smart structures. We aim at reducing the vibration in a specific zone of the smart structure under the disturbance that covers a wide frequency band. Moreover, at this specific zone, neither actuation nor sensing is possible.Here we face several main challenges. First, we need to control the vibration of a specific zone of the structure while we only have access to measurements at other zones. Second, the wide bandwidth of the disturbance implies that numerous modes should be controlled at the same time which requires the use of multiple actuators and sensors. This leads to a MIMO controller which is difficult to obtain using classical controller design methods. Third, the so-called spillover problem must be avoided which is to guarantee the closed-loop stability when the model-based controller is applied on the actual setup. To tackle these challenges, we investigate two control strategies: the centralized control and the distributed control.For centralized control, we propose a methodology that allows us to obtain a simple MIMO controller that accomplishes these challenges. First, several modeling and identification techniques are applied to obtain an accurate low-order model of the smart structure. Then, an H_∞ control based synthesis method with a particularly proposed H_∞ criterion is applied. This H_∞ criterion integrates multiple control objectives, including the main challenges. In particular, the spillover problem is transformed into a robust stability problem and will be guaranteed using this criterion. The obtained H_∞ controller is a standard solution of the H_∞ problem. The final controller is obtained by further simplifying this H_∞ controller without losing the closed-loop stability and degrading the performance. This methodology is validated on a beam structure with piezoelectric transducers and the central zone is where the vibration should be reduced. The effectiveness of the obtained controller is validated by simulations and experiments.For distributed control, we consider the same beam structure and the same control objectives. There exist methods aiming at designing distributed controllers of spatially interconnected system. This research proposes a FEM based method, combined with several model reduction techniques, that allows to spatially discretize the beam structure and deduce the state-space models of interconnected subsystems. The design of distributed controllers will not be tackled in this research

An analytical model of doubly salient switched reluctance machine magnetic noise prediction and a new technique of active noise reduction are proposed. The studied machine is described as well as the analytical expressions permitting the determination of mechanical deformations and acoustic intensity. The main contribution of this research consists in determining analytical expressions of magnetic origin forces which create vibrations and noise. A 2kW 8/6 machine permits to validate several theoretical points such as mechanical resonance frequencies, phase inductances or vibratory and acoustical spectra. Existent noise reduction process are also described as well as influences of geometric parameters - such as teeth or yoke dimensions- on noise. At last, a new technique using current injection into auxiliary windings is performed and validated on an available prototype

The aims of the present PhD thesis are to determine a model that is both sufficiently accurate and numerically exploitable to propose optimal placement of sensors and actuators for active vibration control in a galvanizing line. A continuous hot-dip galvanizing process consists in covering a metal (here: a steel band) by a protective layer of zinc which avoids the corrosion due to the air. The thickness of this layer must be constant to guarantee the mechanical properties and surface condition of the product. In a galvanizing line, the moving steel strip is heated and then immersed in a liquid zinc bath before being wiped out by nozzles projecting air. The air flow, as well as the rotation of the driving rolls, among other things, creates vibrations affecting the wiping process and thus the regularity of the zinc deposit. Active control is therefore necessary, for example by means of electromagnets placed on either side of the moving steel strip. In a first step, a behavioral model of the steel strip taking into account the presence and propagation of vibrations was obtained by spatial discretization of a partial differential equation. This state space model was validated in simulation and experimentally on a pilot galvanizing line of ArcelorMittal Research in Maizières-lès-Metz. Once this model is established, the objective of the study is to find the optimal placement of sensors, to measure the vibrations of the strip as efficiently as possible, but also of actuators to minimize the amplitude of these vibrations by an appropriate control law. These problems of optimal placement are at the heart of the issues of active vibration control and are found in many fields of application. An optimal placement method based on Gramian maximization has been proposed in order to reduce the impact of disturbances on the system. Different control strategies have been considered such as (i) observed state feedback based on Kalman filter and LQ regulator; and (ii) extended observed state feedback to improve the results by also taking into account the disturbance estimation provided by a PI (proportional-integral) observer. Simulation and experimental results illustrate the thesis contributions

Earth observation satellites for meteorological, scientific or military applications sometimes carry infrared imagers. These cameras need to be cooled down to very low temperatures in order to avoid blurry infrared pictures of the Earth, due to the thermal noise of the detector or heat sources nearby. This PhD thesis focuses on a pulse tube cryocooler used in such applications. It deals with induced vibrations as they can destabilize the satellite or make the camera focal plane move. The goals are to understand and reduce the vibrations induced by the pulse tube cryocooler. These PhD works are composed of two main parts. First, the cryocooler is analyzed and modelled to reproduce observed induced vibrations. This global multiphysics model is aimed at identifying dissymmetry, non-linearity and mechanical behaviors which cause vibrations. This approach uses different fields of science such as electromagnetism, mechanics, fluid mechanics and thermodynamics. Sensitivity studies are done and the model is confronted to experiments highlighting measurement tools limits and checking methodologies. Next, vibration reduction using control strategies is studied. The whole control loop is questioned. The improvements proposed concern the vibration sensors, the frequency analysis algorithm, the vibration reduction algorithm and the type of control. Solutions for control, conception and manufacturing resulting from this PhD work offer opportunities to improve the system and lower its cost
