This book was released on 2010 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cette thèse a pour objectif d'apporter une contribution aux travaux déjà menés dans le cadre de commande en vitesse des machines asynchrones avec ou sans capteur mécanique. il s'agit de développer des loi de commande adaptatives floues robustes basées sur le backstepping afin d'assurer les performances de poursuite, tout en respectant l'analyse de la stabilité globale du système étudié. Après avoir donné, dans le premier chapitre , un aperçu sur les techniques répandues dans le cadre de la commande de la machine asynchrone, nous avons mis l'accent sur la modélisation de cette dernière avant de présenter son modèle dynamique en vue de sa commande. Par la suite, nous avons exposé les deux types des approximateurs flous utilisés dans la mise en œuvre de nos approches. Dans les deuxième et troisième chapitres, nous avons présenté une commande stabilisante par backstepping puis des amélioraionns traitant la robustesse, la consommation énergétique et l'élimination du capteur mécanique. Le dernier chapitre a été consacré à la validation expérimentale sur un banc d'essais des approches développées

Book Synopsis A Numerical Investigation of Sound Generation in Supersonic Jet Screech by : Ted A. Manning
Download or read book A Numerical Investigation of Sound Generation in Supersonic Jet Screech written by Ted A. Manning and published by . This book was released on 1999 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The noise of supersonic jet flows is due in part to the interaction between jet instability waves and the jet shock-cell structure. If no countermeasures are taken, the emitted shock-cell noise will re-excite certain instability wave modes at the nozzle lip and cause resonant feedback to occur. This feedback resonance, known as supersonic jet screech, causes the jet to flap violently at discrete frequencies and generate very strong, narrow banded tones. Jet screech has been shown to be a source of acoustic fatigue in the tail and nozzle structures of supersonic aircraft. It is important that methods for predicting the screech amplitude be developed. Screech sound generation is one such element. We isolate the interaction of an unsteady shear layer with a single oblique shock. To obtain an overall understanding of the phenomenon with fewest simplifications, we study this problem through the numerical solution of the Navier Stokes equations. We then consider idealizations which allow us to obtain a similar but wider range of results with specially linearized Euler equations. The findings of these r0sults motivate the use of geometric acoustics to describe the screech generation process. The Navier-Stokes and Euler simulations have revealed important details about the interaction process, how the acoustic field results, and why screech is so loud. The mechanism for sound production is found to be fundamentally different and more efficient when the instability waves are the large vortices typical of screech, than when they are small disturbances. Geometrical acoustics can be used to explain the leakage effect at high instability wave amplitude. We conclude that the mechanism for high amplitude screech generation is an unsteady modification to the velocity field by the instability waves that permits the incident shock to refract through the shear layer.
Book Synopsis Adaptive Harmonic Balance Method for Unsteady, Nonlinear, One- Dimensional Periodic Flows by : Raymond C. Maple

This book was released on 2002-09-01 with total page 167 pages. Available in PDF, EPUB and Kindle. Book excerpt: A new adaptive split-domain harmonic balance computational fluid dynamics (CFD) method is developed to solve highly nonlinear time-periodic flows such as those found in turbomachinery. The basic harmonic balance CFD method transforms an unsteady time-periodic problem into a steady-state problem by assuming a solution in the form of a Fourier series in time. The new method employs a unique multi-domain split-operator solution technique to remove a large-series stability restriction present in previous harmonic balance CFD approaches. In addition, the new method adapts the frequency content to the flow, starting with a small number of Fourier frequencies and augmenting the frequency content in each cell as necessary to capture local flow physics. The method reduces compute times by allowing larger integration time steps, eliminating Fourier transforms, and reducing overall problem size. The stability and accuracy of the method are verified with solutions to the 1-D inviscid Burger's equation and 1-D Euler's equation. Accurate adapted quasi-1-D Euler solutions for a supersonic/subsonic diverging nozzle with periodic unsteady outflow conditions are generated in 86% less time than an equivalent non-adapted split-domain solution, demonstrating the performance benefit of matching frequency content to the local flow conditions.
