Повний текст джерелаThis subject contributes to the modeling and control of a wind conversion system based on a Double Excitation Synchronous Generator (DESG). The degree of freedom provided by the wound excitation allows the improvement of the energy efficiency on the operation’s cycles with random solicitations, as it is the case for wind turbines.The aim of this research is to implement robust control techniques for the DESG in order to optimize its aerodynamic efficiency and to reduce its mechanical loads. In this context, a hybrid generator connected to an isolated load for wind applications is presented. First, linear models are established. These models are used to set up the appropriate control structures from both an electrical and mechanical point of view. At the same time, very complete nonlinear models are developed allowing a validation in an advanced simulation platform taking into account the space harmonics of the generator, the switching effects of the converters and the torsional effects on the shaft. Moreover, a 3 kW wind emulator is built to evaluate the contribution of the hybrid generator in the wind conversion systems field and then improve the synthesized controllers. Two robust control strategies for a hybrid machine are implemented and a comparison between a CRONE controller and a H∞ controller is presented. Satisfying results are obtained with a better performance for the CRONE regulator compared to H∞ one. In addition to the problem of optimizing the production of the wind energy conversion system, attempts have also been made to reduce the generator harmonic distortion ratios by using two solutions: passive filtering and reduction of the electromagnetic torque ripple by acting on the excitation current. Although there are improvements at high rotation speeds, these solutions are not sufficient for a connection of the proposed architecture to the grid.Once the applicability of the DESG in the wind energy field has been proven in the case of a 3 kW wind conversion system, we have considered a more realistic case. To this end, we have interfaced the developed advanced electric model with an aeroelastic model available on the FAST software, to take into account the mechanical couplings and the flexibilities. The turbine chosen for the study is the WindPACT 1.5MW turbine. In this part, robust controllers dealing with the reduction of mechanical fatigue are developed.The model of WindPACT turbine based on the hybrid generator is finally connected to the grid and the control laws necessary for this connection are implemented and validated under the Matlab Simulink platform

Impulsive noise is a natural phenomenon in everyday experience. Impulsive noise can be analogous to discontinuities or a drastic change in natural progressions of events. Specifically in this research the disrupting events can occur in signals such as speech, power transmission, stock market, communication systems, etc. Sudden power outage due to lighting, maintenance or other catastrophic events are some of the reasons why we may experience performance degradation in our electronic devices. Another example of impulsive noise is when we play an old damaged vinyl records, which results in annoying clicking sounds. At the time instance of each click, the true music or speech or simply the audible waveform is completely destroyed. Other examples of impulse noise is a sudden crash in the stock market; a sudden dive in the market can destroy the regression and future predictions. Unfortunately, in the presence of impulsive noise, classical methods methods are unable to filter out the impulse corruptions. The intended filtering objective of this dissertation is specific, but not limited, to speech signal processing. Specifically, research different filter model to determine the optimum method of eliminating impulsive noise in speech. Note, that the optimal filter model is different for time series signal model such as speech, stock market, power systems, etc. In our studies we have shown that our speech filter method outperforms the state of the art algorithms. Another major contribution of our research is in speech compression algorithm that is robust to impulse noise in speech. In digital signal processing, a compression method entails in representing the same signal with less data and yet convey the the same same message as the original signal. For example, human auditory system can produce sounds in the range of approximately 60 Hz and 3500 Hz, another word speech can occupy approximately 4000 Hz in frequency space. So the challenge is, can we compress speech in one of half of that space, or even less. This is a very attractive proposition because frequency space is limited but the wireless service providers desires to service as many users as possible without sacrificing quality and ultimately maximize the bottom line. Encoding impulse corrupted speech produces harsh quality of synthesized audio. We have shown if the encoding is done with the proposed method, synthesized audio quality is far superior to the sate of the art.

Повний текст джерелаIn this thesis, we propose a Lyapunov based approaches to address some distributedsolutions to multi-agent coordination problems, more precisely, we consider a groupof agents modeled as nonholonomic mobile robots, we provide a distributed controllaws in order to solve the leader-follower and the leaderless consensus problems under different assumptions on the communication graph topology and on the leader’strajectories. The originality of this work relies on the closed-loop analysis approach, that is, it consists on transforming the last two problems into a global stabilization problem of an invariant set. The stability analysis is mainly based on the construction of strict Lyapunov functions and strict Lyapunov-Krasovskii functionals for a classes of nonlinear time-varying and/or delayed systems

A simple, compact, yet powerful robotic winch, called "Winch-Bot," is presented in this thesis. The Winch-Bot is an underactuated robot having only one controllable axis. Although hanging a load with merely one cable, it is capable of moving it in a large workspace by swinging the load dynamically based on parametric self-excitation. The generated trajectories can be used for a variety of tasks, from moving material to cyclic inspection of surfaces. The basic principle and design concept of the Winch-Bot are first described, followed by dynamic modeling and analysis. Two trajectory generation problems are solved. One is point-to-point transfer of a load, and the other is the tracking of a continuous path. It will be shown that the system can track a given geometric trajectory, although the tracking velocity cannot be determined arbitrarily due to the underactuated nature of dynamics. A prototype Winch-Bot is designed and built, and point-to-point, continuous path, and parametric excitation control are implemented.

Повний текст джерелаIn this masters thesis we consider a method for experimental identification of the inertial parameters of an industrial robot, using measured torques and joint angles. A dynamic model of the first three joints of the robot has been identified.
To achieve good identification results, it is important to carefully choose the trajectory for the experimental identification. A method to generate trajectories using two suggested design criteria has been used and evaluated using an ABB industrial robot, and one of them yields good identification results.
Denna rapport behandlar en metod för experimentell identifiering av en stelkroppsmodell för en industrirobot. Metoden använder sig av uppmätta moment och armvinklar för att identifiera parametrarna i en dynamikmodell för robotens tre huvudaxlar.
För att erhålla bra identifieringsresultat är det viktigt att välja en lämplig identifieringsbana och i detta arbete har en metod för generering av banor använts och utvärderats för två olika designkriterier. Experiment har utförts på en industrirobot från ABB och vi har erhållit goda identifieringsresultat med ett av designkriterierna.
