Full textFloating wind turbines allow the use of the abundant wind resource in ocean area and are considered as a promising solution of renewable energy. However, due to the additional dynamics (especially the platform pitch motion) introduced by the floating platform, the control of a floating wind turbine must take such pitch motion into consideration to stabilize the system meanwhile optimizing the power output. This work is dedicated to the nonlinear control of floating wind turbines in region III, this class of controllers requiring reduced knowledge of system modeling and parameter. The control objectives are to maintain the power output at its rated value, to reduce the platform pitch motion and to limit the fatigue load. Firstly, a simplified adaptive super-twisting is proposed. Then, by using collective blade pitch control, this algorithm and other adaptive high order sliding model algorithms are applied on a nonlinear floating wind turbine model. Secondly, a permanent magnet synchronous generator is supposed to be installed in the floating wind turbine. Both collective blade pitch control and generator torque control based on adaptive high-order sliding mode control are used to achieve the control objectives. Thirdly, individual blade pitch control combined with collective blade pitch control is employed. Such algorithm further reduces the fatigue load of blades. Finally, the proposed simplified adaptive super-twisting algorithm is validated on an experimental floating wind turbine set-up (with a spar-buoy platform) in a wave tank, and the control performances are evaluated versus linear control approaches such as gain-scheduled PI and linear–quadratic regulators

Full textWind energy is a clean and renewable source of energy that remains one of the solutions to cut carbon emissions and curb global warming in the field of power generation. The present thesis objective is the optimisation of wind energy production by the all eviation of blade load fluctuations induced by shear and turbulence in the atmospheric boundary layer. These fluctuations increase the blade fatigue and reduce the life duration of the rotors.This load fluctuation all eviation is assessed with an experimental approach and at a laboratory scale. Two not conventional flow control strategies, plasma actuators and fluidic jets, are implemented and tested in the controlled environment of a wind-tunnel to perform a circulation control by acting in the vicinity of the rounded trailing-edge of the blade in order to modify its lift force.In the scope of the SMARTEOLE project, both plasma and fluidic strategies are, as a first step, tested in parallel on a 2D-airfoil. For this thesis, plasma actuators are implemented over the airfoil trailing-edge to increase ordecrease the lift force. Airfoil performances are indeed modified in the linear part of the lift curve. For efficiency and reliability reasons, it is chosen to pursue the work towards the rotational configuration with the fluidic strategy. Blades are then manufactured and tested first in a translational configuration to evaluate the potentialof the fluidic actuation without rotational effects. Then, blades are mounted in the wind turbine bench of the laboratory. The effects of the actuation are demonstrated through surface pressure and flapwise bending moment measurements. Actuation shows important fatigue reduction motivating the pursue of the investigations on active flow control applied to wind turbine blades

Full textThere is a conviction in the engineer science field which led in thinking that any divergence between numerical simulation and experimental results is necessarily due to an imperfect modelisation of the converter or to an epiphenomenon manifestation ordinarily neglected. It's the situation for example of the stepping motor in the instable operation zone where the dynamics isn't periodic anymore. After having built and simulated a generic model validated by experimental observations, we demonstrate that these aperiodical behaviours are intrinsic properties of the converter. To do so, we have had to design special tools adapted to the specific chaotic characteristics of that electromechanical converter. We have built an automatic control and acquisition tool which assure a low noise level and a maximum of reproducibility of the experimental results. We have also written some simulation software in object C language because solutions obtained with generalist numerical tools on systems near the stability limits are usually not satisfying. With both theoretical and experimental approaches, we propose a systematic study of the dynamics exhibited by the step by step motor. That accurate knowledge of the motor behaviour allow us, at last, to propose a simple and economical control strategy without any position detector, in order to obtain a periodic motor behaviour in zones where it naturally isn't. This allows us to extend, at low cost, the useful range, in the engineer meaning, of this converter

Full textIn order to understand the etiology of falls in the elderly, studies in the field of biomechanics have mainly focused on assessing balance abilities, relying on the analysis of linear body movements. However, maintaining balance during our various motor tasks requires both appropriate control of linear movements and angular (rotational) movements of body segments. Thus, this doctoral work aims to identify and understand changes in the control of angular body movements in old adults through the study of whole-body angular momentum, which is recognized as a mechanical parameter highly controlled by the central nervous system to maintain balance. Our studies reveal that during the volitional stepping task, old adults exhibit an alteration in the control of the whole-body angular momentum. Overall, our results show that old adults have a higher range of whole-body angular momentum than their younger counterparts – particularly in the sagittal plane – and this is exacerbated with the increase in progression velocity. Furthermore, our results highlight that this age-related changes in the control of whole-body angular momentum is directly ascribed to changes in segmental angular momenta, with old adults having higher trunk and lower limb angular momenta than young adults. Finally, we observed a relationship between the range of whole-body angular momentum during the stepping task and measurements of muscle strength and balance in young and old adults. These results suggest that age-related changes in the control of whole-body angular momentum, which may impose greater challenge for balance control and potentially a greater risk of fallingduring the volitional stepping task in old adults, can be partially attributed to the decline in lower limb muscle strength and the impairment of other systems involved in balance control with aging. Together, our results contribute to a better understanding of the mechanisms underlying impaired balance control in old adults and provide a basis for future studies to reduce the incidence of falls in this population

Full textThe precise role of the basal ganglia in the control of motor actions is still under debate. We designed a well-controlled start-stop running paradigm for mice, that enabled to quantify the kinematic parameters associated with motor execution. Extracellular recordings demonstrated that our task massively recruited 8 different functional striatal classes that modulated their activity at distinct phases of the sequential action and immobility. The “what” group comprised Beginning and End neurons which were specifically tuned at the beginning or at the end of the motor sequence, respectively. The “how” group was the most representative and comprised Running, Onset and Offset cells which, cooperatively represented the entire execution of the motor sequence and were well correlated with speed performance. Strikingly, we also reported the presence of the Immobility cells that specifically fired during immobility periods. Comparison of performances during good trials versus spontaneous runs showed that the fraction of the different striatal classes remained stable. However, the fraction of cells with significant sequence-related modulation was prominently decreased in spontaneous compared to good trial runs, and the activity of the Running cells was less correlated with animal's running speed and duration. Our data are consistent with a basal ganglia model where striatal activity is coordinately organized in a temporally precise manner to initiate, maintain and terminate motor sequences. Ongoing experiments with optogenetics techniques (developed during this thesis) will confirm inferred causal relationships of striatal activity to specific motor implementations

Full textSpace missions are arousing renewed interest in these recent years. However, when coming to the entryinto the atmosphere, major issues are still to be considered. To answer this problem, a new Entry DescentLanding technique is proposed: plasma actuation to increase the drag force over the vehicle body and thus,decrease its speed. In this thesis, a plasma actuator is tested in three supersonic rarefied flows (N1(M2-8Pa), N2(M4-8Pa) and N3(M4-71Pa)) and a hypersonic one (M20-0.062Pa), all generated by the wind tunnelMARHy.The plasma actuator induces flow modifications over the studied model, such as a change in the shock waveshape and an increase in the shock wave angle. In order to better understand the phenomena governingthese modifications, Pitot pressure, surface and gas temperature, electron data and spectroscopicmeasurements were analyzed. The results shown that two types of effects are involved: thermal (bulk andsurface) and ionization. Moreover, it was demonstrated that these effects had not the same importancedepending on the flow conditions.The plasma actuator was also modified in order to improve it. In particular, two types of generators wereused to biase the cathode: DC and pulsed. Finally, it was shown that, for a discharge power of 80 W, a 13%increase in the drag force could be expected and thus, a decrease in the heat load over the model body ofmore than 25%. Therefore, plasma actuators seem to be promising applications for space missions andatmospheric entries

Full text"Conventional" or certified repair procedures for composite structures (i. E. Patches) are usually time-consuming, performed by highly qualified staff and seem immoderate regarding the most common damage found in aeronautics due to low energy impact. A cost-effective and simple repair method based on liquid resin infiltration in the induced crack net is proposed. An analytical model based on damage geometry and physical chemistry properties, is developed to verify the resin infiltration capabilities. An experimental protocol has been developed to identify those properties with conditions similar to the infiltration process (roughness, temperature,. . . ). An experimental set up has been manufactured and different configurations (injection pressure level, infiltration resin toughness. . . ) are studied. Non destructive testing, like ultrasonic inspection, combined to micrographic inspection show good experimental infiltration capabilities. To initiate the validation procedure of this repair, the second part of this work deals with the mechanical behaviour and strength of the repair with experimental tests campaign. Numerical models are used for analysis and understanding. Two different scales are considered at interface (material) and structural level. Fracture Mechanics tests are performed with classical tests such as DCB or ENF, and a new original one, Tensile Flexure test on Notched Specimen (TFNS test), to characterize and identify the repaired interface properties. For their severity regarding composite materials behaviour, both CAI and re-indentation (in-plane and out-of-plane solicitation representative of real loading conditions) were performed on repaired samples. Those complementary tests show that this infiltration repair method restores mechanical properties when proper toughened resins are used
