Camino, Jean-Thomas. "Co-optimisation charge utile satellite et système télécom." Thesis, Toulouse 3, 2017. http://www.theses.fr/2017TOU30401.
Повний текст джерелаThe continuous growth in telecommunication needs in our society translates into a series of technical challenges for the systems that provide such services, whether it is television broadcasting, telephone, or data exchange. The telecommunication satellites are particularly concerned by this need for innovation, both on the embarked technologies but also on the way the resulting resources are exploited for the end users. On the latter point, for a telecommunication mission defined precisely in terms of service zone, type, quantity and quality of service, one has to be able to size as adequately as possible the telecommunication satellite payload, under the several constraints it is subject to: mass, volume, cost, and power consumption of the embarked hardware. This thesis develops an algorithmic approach for a such a sizing in the particular case of the telecommunication systems that are said to be "multi-beam". A global optimization process of these satellite system is proposed. It relies on a decomposition into a set of mathematical problems whose respective complexities, reduced with respect to the original problem, allow to reasonably aim for efficient algorithmic solutions. This work allowed to identify two key problems in this satellite payload sizing, addressed through an operations research angle: the beam layout optimization and the frequency plan optimization. This first beam layout problem under payload constraints has been an occasion to propose novel ways to handle Euclidean norm constraints on continuous variables for non-convex non-linear mixed programs. These techniques have been then successfully applied in for the generation of solutions to this first problem that fully exploits the mixed integer linear programming formalism. Then, a novel exploitation of some of the properties of the k-means clustering has been proposed as it allows to simplify these mathematical models and therefore accelerate the beam layout optimization. These mathematical programming algorithms have been then compared to a greedy heuristic developed during this thesis work. The second central sizing problem that has been identified is the frequency plan definition. It consists in a resource allocation of on-board satellite resources to the several beams that have been defined in the preceding beam layout optimization problem. With an objective of minimizing the number of a certain type of hardware to be embarked on the payload, the satisfaction of the telecommunication mission defined by an individual demand of all the end users on the ground is aimed. This complex problem itself lead to a decomposition into two sub-problems of frequency and on-board payload hardware allocation, that are treated with constraints programming and integer linear programming, exploiting theoretical results that are useful both at the problem modeling and problem solving levels

Повний текст джерелаSpace launchers undergo a certain amount of complex excitations during their lifecycle. These excitations are transmitted to the payload in a structure-born or air-born way. To improve the dynamic behaviour and thus ensure the protection of the payload, secondary systems must be added to the launcher – indeed, the architecture of the launcher is fixed at the beginning of the project. The essential part of this thesis work is dedicated to the optimal fitting of a system capable of reducing the vibration response of the payload, using appropriate models. Therefore a double modal synthesis method is implemented, allowing to calculate the vibrational response of the structure with reduced bases and offering improved performances over conventional methods. The addition of a local damping device requires the consideration of one or more structural modifications in the model, a dedicated method is thus developped along with a specific continuation algorithm. A friction damper is retained, a prototype is designed and built. It is first characterized alone ; the identified behaviour is that of a spring in series with a dry friction element, a simple Coulomb friction law enables to reproduce the experimental curves. A scale model of the launcher’s last stage is designed and built. The friction device is then mounted inside the scale model and leads to a significant reduction of the payload vibration levels

Повний текст джерелаThe filters and the output multiplexers of payload of satellite are in the beginning of improvement of performance, time of design and time of realization. The research tasks presented here are on the development of methods of assistance to the electromagnetic design of these devices. The methods of assistance to the electromagnetic design of the filters, used and developed here, make it possible, on the one hand, to obtain final dimensions of the filters for an experimental realization (machining only one set of cavities and irises). They also make it possible to characterize quickly and efficiently the filters in an electromagnetic way. These methods were validated by the design of two filters in dual-mode cavities functionning in Ku-band and in Ka-band and were validated with experimental results. The electromagnetic characterization of the filters permits to consider the analysis of multiplexers. It was at the origin of the development of methods of assistance to the electromagnetic design of multiplexers. The methods presented contribute to the conception of multiplexers by modelling the dephasing introduced the excitation systems. The second axis presented permits to compensate for the influence of spurious modes disturbing the response of the OMUX. Then, these methods make it possible to consider a fast and rigorous electromagnetic characterization of multiplexers and thus, to answer the problems involved in the growing number of channels which constitute it

Повний текст джерелаThis thesis is a research in methodology of evaluation of the professional practices. The original approach consists in proposing a method making it possible to achieve a double goal: on the one hand to immediately use the results for the benefit of the patients included in the evaluation and on the other hand to answer the obligation of evaluation of the professional practices such as she is currently recommended by the High Authority of Health (HAS). Continuing a work initiated on the methodology of the investigations of practices applied to the evaluation of the practices of care, and within the framework of the Grouping of Public Interest "ReQua" of Franche-comté, we checked with studies on various topics (psychiatry, nutrition, geriatrics) that an evaluation of the occupational practices pursuing the double goal describes higher, feasible, acceptable by the professionals and was recognized by the HAS

Повний текст джерелаThis PhD work concerns the elaboration of a method to verify the seismic sustainability of shallow foundations considering 2011 seismic zoning of France. It is a part of a research contract between EDF CEIDRE and IFSTTAR.To this end, a macroelement based model is developed in order to assess nonlinear soil structure interaction. The elastoplastic formulation of the macroelement constitutive model is compliant with the classical plasticity theory. The formulations for the plastic mechanisms are inspired from the applied standard (Eurocodes 7 & 8). The rate dependent response and the effects of the embedment and the soil inertia efforts are taken into account. The parameters for the constitutive model are defined from laboratory or field tests, or calibrated from static finite element method simulations. The calculation cost is significantly reduced due to the simplified modelling of the soil and its non linearities. Another advantage is that the macroelement based tool is formulated in terms of generalized variables (forces and displacements): this promotes its application in the verification of the sustainability of shallow foundations (bearing capacity, sliding, overturning, settlements, translations, rotations and distortions).The macroelement is implemented in the Finite Element software CESAR LCPC. It allows to simulate the static and the seismic behaviour of a shallow foundation. Three alternative approaches to assess SSI through this model are possible. These alternative approaches are explained and tested under static and seismic load.Then, it is used to perform parametric studies involving various input motions derived from earthquake recordings. The seismic response of a simple structure is studied with respect to the input motion key parameters.Finally, the static and seismic behaviour of a real structure is analysed. The structure is founded on a large raft foundation laying on a multi-layered soil. The seismic hazard is defined by five 0.4 g-PGA accelerograms. Verification to the applied standards is performed on the base of the simulation results, considering many features of the seismic behaviour

Повний текст джерелаDesign by analysis of pressure vessels is placed within guidelines. Two methodologies are currently considered in international standards. The first one was proposed in the 60’ : it considers an elastic stress classification, depending on the nature of loads. It nowadays suffers from obsolescence, as technological demand and computational facilities increased considerably. The – much more recent – second one deals with elastoplastic calculations : it is based on limit and shakedown analysis theory, but causes applicative difficulties. The work achieved in this thesis begins with a state of the art, dealing with legal aspects of this industry, and detailing commonly-applied design rules and criteria. Several failure modes were identified, and the study focuses on two of them : gross plastic deformation and ratchet. Direct methods were selected for their relevance toward design considerations. Currently developed in research labs, they were studied, implemented, tested, and criteria were modified so as to take into account safety margins. Three solutions were explored : direct cyclic analysis, yield modification, and elastic compensation. For comparison purposes, methodologies were evaluated on academic and realistic cases. Accuracy and computational time were measured, along with the relation between these datas. Trends could be established, relating the pertinent use of a methodology to a problem complexity

Повний текст джерелаFor every electrical network, sizing electrical sources is a critical challenge. This is even more important when the electrical network is an on-board one where it has to be self-sufficient, with very high constraints on volume and mass. Following several measurement campaigns on aircrafts, it has been shown that the electrical load analysis is over estimating the power needed during flights. Beyond the reassuring aspect, this observation can show some other problems while thinking about more electrical aircrafts where higher power are planned. With statistical approach of power flows, the present work targets to evaluate with more accuracy the electrical power needed to supply the network. First of all, study will focus on probabilistic load models to describe electrical power for each load on the network. Associated with a Monte Carlo algorithm, this method give results on the electrical power needed by the electrical network, allowing us to perform a sizing of the sources. Then, a dynamic probabilistic load model is developed to take into account duration of electrical powers. With this new model and the information of electrical overload capability of generators, it is possible to size their rate power under the maximum consumed electrical power still ensuring that overloads are, theoretically, acceptable. Applied on the A380, this approach shows potential savings that are not to neglect. Scenarios stemming from these new models could be used to perform thermal simulation on the electrical generators to check the potential overheating

Повний текст джерелаDifferential phase shifters (DPS) are used in in parallel structures such as Butler matrices, to avoid losses on signal recombination to avoid losses on signal recombination. The DPS are generally composed of two transmission lines out of phase with each other. The phase shift control in these devices line length adjustment, or by integrating elements such as coupled lines or stubs. However, these solutions do not meet the many specifications of the phase shifter in an industrial context. Metamaterials, which are known as structures composed of several small elements, with unique properties, could enable phase shift control with more degrees of freedom. To this end, metamaterials such as composite lines have already been investigated. However they exploit a particular case of metamaterial, the balanced line, to design phase shifters. This thesis objective is to design metamaterial phase shifters by exploiting as much as possible their degrees of freedom, namely without limiting the phase shift design to balanced lines. For this purpose, we have implemented a dedicated design method to obtain from phase shifter specifications solutions with adequate performances for integration on very constrained industrial systems. This method has been illustrated and validated through an application to a case of 180° phase shifter with a 20% bandwidth in C band [4.95GHz -6.05GHz]

Повний текст джерелаThis thesis is a contribution to the power sizing and the control of a Cascaded Doubly Fed Induction Generator (CDFIG). The machine model for simulation is based on a modular representation, derived from the Park model of two distinct Doubly Fed Induction Machines expressed in their own reference frames. The dynamic model of the cascaded machine is then extended to be described in a unified reference frame. This representation is convenient for the sizing of the machine and for the design of the controller. The steady state power operating margins of the cascaded machine are investigated. A generic analytic method is suggested to derive the active-reactive power domain. The limit curves are defined in terms of the rated quantities of the machine. The study takes into account the magnetic circuit saturation effect. It is proven that the power capability of the machine is determined by the stator current maximum values and is subject to several limitations. The analytical approach is tested and validated by experimental measurements. The CDFIG is controlled in grid-connected and standalone operation modes. In grid-connected application, the attention is paid to high power wind generation systems. A new maximum power tracking of a variable speed wind turbine is suggested. The generating plant is carried to provide a quasi-constant maximum power regardless wind fluctuations. In addition to active power optimization the power factor is adjusted according to the grid code requirements and the operating domain of the integrated unit. A virtual flux oriented vector control is applied for the decoupled regulation of active and reactive powers, leading to grid voltage sensorless operation. In standalone operating mode, the study treats in particular the embedded aircraft power system generation. Two distribution networks are considered: constant frequency AC network and DC network. In both cases, the control aims to maintain a constant output voltage. The operation of the CDFIG supplying unbalanced three-phase load is further explored. Control schemes to cope with unbalanced stator voltage conditions are developed. Two compensation methods are elaborated: the first dealing with dual rotating frames and the second is based on repetitive controller. Simulations with Matlab/Simulink software and experiments validate the control approaches

Повний текст джерелаThe research presented in this thesis aims at providing a strategic vision for the integration of distributed generators (DGs) into grid networks. This work focuses the optimal location of the connection point, dimensioning and type of production in order to maximize the benefits of DGs and minimize power losses in the networks. The work also concerns the impact of the variability of the load and the production in the planning and the operational management of the networks. First, algorithms have been developed for power flow studies in power systems using the Schur complement method and the "Run Length Encoding" method. Then, losses were estimated in the calculation of power output by developing a simple, efficient and flexible linear model. Subsequently, decentralized outputs connected to the electrical networks were modeled using a method that merges Kalman filters and graph theory in order to estimate the optimal size of decentralized production. A method which consists of two steps is proposed. In the first step, the graphical method is used to generate the incident matrix to construct the linear model and in the second step a Kalman algorithm is applied to obtain the optimal decentralized production size for each busbar. The challenges of using decentralized production have been addressed to minimize the objective function (real power losses) by taking into account the capacity of the decentralized productions, transmission line capacity and voltage profile constraints. The genetic algorithms and optimization techniques such as the method of interior points have been proposed to determine locally and globally the optimal dimensioning and the optimal location of the decentralized productions in the electrical networks. Finally, an active load model was designed to study different types of load curves (residential, commercial and industrial). We have also developed simulation algorithms to study the integration of wind farms in power grids. We have designed analytical methods to select the size and location of a wind farm, based on the reduction of active power losses. We have shown that variations in the mean annual wind speed could have a significant effect on the calculations of active power losses. Analytical methods and simulation algorithms were developed under Matlab / Simulink

Повний текст джерелаNowadays, Satellite telecommunications are becoming very popular and the number of subscribers worldwide is always growing. Wherever the optical fiber cannot be deployed, they are a reliable way to provide very high data rates to the users, whose activities are becoming more and more bandwidth-hungry (HD video, video conferencing, downloading, cloud computing, online games ...). They also guarantee very large coverage areas. In order to follow the market needs satellite payload designers have to increase the number of on-board equipment, which affects the volume and mass of the systems and therefore the launching cost. One of the solutions to solve the problem consists in using optical technologies. It has been demonstrated by Thales Alenia Space that In the case of a reference signal distribution system for 64 devices, a weight reduction of about 70% could be obtained. In this context we have developed 7 RF frequencydown-converters based on photonic semiconductor components. The down-converters are key components of satellite payloads, as their aim is to isolate uplink transmissions (ground to satellite) and downlink (satellite to ground) to avoid interference. Performance of the 7 architectures, incorporating electro-absorption modulators (EAM) and semiconductor optical amplifiers (SOA) were evaluated through various simulations and by calculating the conversion gain, noise figure, RF/IF and LO/IF isolations, the C/I3 ratio and the coordinates of the third order intercept point. We obtained interesting results, first data for futur works,and showed that these converters are compatible with many frequency plans in Ku/Ku, ku+/Ku, and Ka/Ka bands. Manipulations were also led and validated the theoretical models used in simulations

Повний текст джерелаThe high capabilities of current and future 5G communication satellite links lead the processed signals in the payloads to simultaneously exhibit large amplitude variations (PAPR>10dB) and wide instantaneous bandwidths (BW>1GHz). Within the microwave transmission subsystem, the operation of the power amplification stage is highly constrained by the transmitted waveforms, it is one of the most energy-consuming module of the payload affecting as well the integrity of the transmitted signal. In this context, the functions dedicated to digital signal processing and currently implemented by the digital processor (such as filtering, channeling, and possibly the demodulation and regeneration of baseband signals) embedded in the payloads, represent a potential solution that would reduce the constraints reported on the power amplification function and help to manage the allocated power ressource. This work proposes a study on the capability of dual input power amplifier architectures in order to manage the efficiency-linearity trade-off over a wide bandwidth. This study is carried out on a 20W GaN Doherty demonstrator operating in C band. The combination of the output signals on the RF load is managed by an optimal amplitude and phase distribution that is digitally controlled at the input. Firstly, a wideband design methodology of Doherty amplifier is introduced and validated on a C band demonstrator. In a second time the experimental tool allowing the extraction of amplitude and phase input distributions is presented, the dual input characterization is achieved and compared with simulation results. Finally, in perspective of this work, a preliminary study of the capabilities of the digital Doherty for the management of an output load mismatch (VSWR management) is carried out and the results are put forward

Повний текст джерелаIn this thesis, conducted with Renault in the context of a kitting automation project, we are interested in the optimisation of kitting processes in terms of cycle time maximisation. To do so, we study different configurations of hybrid robot-operator kitting systems where robots (two types of robots considered) and operators are connected in series by an intermediate buffer (to decouple their activities). The robotic kitting area starts the preparation of kits then the operators in the manual kitting area retrieve the preparation of robots and complete with the remaining parts.Our objective is to develop a decision-making tool that assesses the hybrid system performance in a given configuration (layout, picking policy, etc.).First, through a modelling of elementary kitting operations performed by robots and operators (pick and place, travel, etc.), we develop a cycle time model to assess the performance of hybrid kitting systems. Then, we develop an assignment model that assigns parts (formulated as a mixed integer linear programming (MILP) problem) either to robotic or manual kitting areas with the objective of minimising cycle times and balancing workload between them. The model is applied to two case studies pertaining to a Renault plant. This analysis identifies the parameters that influence cycle times and the choice between robotic and manual kitting. Finally, we develop a simulation model to find the optimal buffer size between robotic and manual kitting so that throughput is maximised

Повний текст джерелаNowadays, the radioelectric charac-teristics of satellites are directly measured by means of a com-pact range basis. However, the limits of these bases are affected by the growth of the satellite dimensions, in addition to the number and the complexity of the integrated an-tennas.On the other hand, near field techniques formed a promising solution under the planar range form. These techniques consist of measuring the radiated field near the source and accordingly deduce the far field by the means of mathemati-cal analysis.The purpose of this thesis is to adapt near field techniques for testing telecommunication satel-lites. In fact, these techniques are widelyused for antenna pattern measurements. However, a theoretical development has to be completed and measurement methods need to be proposed for testing all payload parameters. Unfortunately, specific difficulties related to the satellite function (transponder) and the limited access to antennas and satellite electronics have to be taken into account in the implementation of these measurement methodologies.Finally, the near field measurements are affected by many causes of errors. The identification of the error sources and the evaluation of their contribution to the final results constitute an important part of the thesis work. The global study allows dimensioning a complete measurement system with a good optimization
