Book Synopsis Commande multivariable de la pression d'injection dans un moteur diesel Common Rail by : Christophe Gauthier
Download or read book Commande multivariable de la pression d'injection dans un moteur diesel Common Rail written by Christophe Gauthier and published by . This book was released on 2007 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: Les normes sur les émissions de polluants des automobiles sont de plus en plus sévères. Les moteurs à injection directe à rampe commune permettent d'atteindre ces exigences notamment grâce à l'injection du carburant à très haute pression. Cette pression varie de 200 à 1600 bar selon le point de fonctionnement du véhicule. L'objectif des travaux de thèse est de réaliser le contrôle de la pression du carburant avec deux contraintes principales : proposer une méthodologie de calibration du contrôleur à partir des caractéristiques techniques du système d'injection et améliorer à la fois la performance et la robustesse du contrôle. Les travaux réalisés se décomposent comme suit : étude du système d'injection et développement d'un modèle de connaissance ; développement des stratégies et des lois de commande ; mise en application sur véhicule. Les essais réalisés sur véhicule ont montré une amélioration des performances et de la robustesse du contrôle de la pression du carburant obtenue par la proposition d'une nouvelle méthodologie de calibration. Celle-ci est basée par l'obtention du contrôleur à partir des caractéristiques techniques du système d'injection et par l'utilisation de lois de commande avancées (commande H8 pour les systèmes Linéaires à Paramètres Variants (LPV)). En particulier l'approche basée sur l'utilisation des Transformations Linéaires Fractionnelles (LFT) a été considérée.

Book Synopsis Modeling and Identification of Linear Parameter-Varying Systems by : Roland Toth
Download or read book Modeling and Identification of Linear Parameter-Varying Systems written by Roland Toth and published by Springer Science & Business Media. This book was released on 2010-06-13 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: Through the past 20 years, the framework of Linear Parameter-Varying (LPV) systems has become a promising system theoretical approach to h- dle the controlof mildly nonlinear and especially position dependent systems which are common in mechatronic applications and in the process ind- try. The birth of this system class was initiated by the need of engineers to achieve better performance for nonlinear and time-varying dynamics, c- mon in many industrial applications, than what the classical framework of Linear Time-Invariant (LTI) control can provide. However, it was also a p- mary goal to preserve simplicity and “re-use” the powerful LTI results by extending them to the LPV case. The progress continued according to this philosophy and LPV control has become a well established ?eld with many promising applications. Unfortunately, modeling of LPV systems, especially based on measured data (which is called system identi?cation) has seen a limited development sincethebirthoftheframework. Currentlythisbottleneck oftheLPVfra- work is halting the transfer of the LPV theory into industrial use. Without good models that ful?ll the expectations of the users and without the und- standing how these models correspond to the dynamics of the application, it is di?cult to design high performance LPV control solutions. This book aims to bridge the gap between modeling and control by investigating the fundamental questions of LPV modeling and identi?cation. It explores the missing details of the LPV system theory that have hindered the formu- tion of a well established identi?cation framework.

Book Synopsis Robust Control and Linear Parameter Varying Approaches by : Olivier Sename
Download or read book Robust Control and Linear Parameter Varying Approaches written by Olivier Sename and published by Springer. This book was released on 2013-02-01 with total page 402 pages. Available in PDF, EPUB and Kindle. Book excerpt: Vehicles are complex systems (non-linear, multi-variable) where the abundance of embedded controllers should ensure better security. This book aims at emphasizing the interest and potential of Linear Parameter Varying methods within the framework of vehicle dynamics, e.g. proposed control-oriented model, complex enough to handle some system non linearities but still simple for control or observer design, take into account the adaptability of the vehicle's response to driving situations, to the driver request and/or to the road sollicitations, manage interactions between various actuators to optimize the dynamic behavior of vehicles. This book results from the 32th International Summer School in Automatic that held in Grenoble, France, in September 2011, where recent methods (based on robust control and LPV technics), then applied to the control of vehicle dynamics, have been presented. After some theoretical background and a view on some recent works on LPV approaches (for modelling, analysis, control, observation and diagnosis), the main emphasis is put on road vehicles but some illustrations are concerned with railway, aerospace and underwater vehicles. The main objective of the book is to demonstrate the value of this approach for controlling the dynamic behavior of vehicles. It presents, in a rm way, background and new results on LPV methods and their application to vehicle dynamics.

Book Synopsis Rotordynamics of Automotive Turbochargers by : Hung Nguyen-Schäfer
Download or read book Rotordynamics of Automotive Turbochargers written by Hung Nguyen-Schäfer and published by Springer. This book was released on 2015-05-15 with total page 367 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rotordynamics of automotive turbochargers is dealt with in this book encompassing the widely working field of small turbomachines under real operating conditions at the very high rotor speeds up to 300000 rpm. The broadly interdisciplinary field of turbocharger rotordynamics involves 1) Thermodynamics and Turbo-Matching of Turbochargers 2) Dynamics of Turbomachinery 3) Stability Analysis of Linear Rotordynamics with the Eigenvalue Theory 4) Stability Analysis of Nonlinear Rotordynamics with the Bifurcation Theory 5) Bearing Dynamics of the Oil Film using the Two-Phase Reynolds Equation 6) Computation of Nonlinear Responses of a Turbocharger Rotor 7) Aero and Vibroacoustics of Turbochargers 8) Shop and Trim Balancing at Two Planes of the Rotor 9) Tribology of the Bearing Surface Roughness 10) Design of Turbocharger Platforms using the Similarity Laws The rotor response of an automotive turbocharger at high rotor speeds is studied analytically, computationally, and experimentally. Due to the nonlinear characteristics of the oil-film bearings, some nonlinear responses of the rotor besides the harmonic response 1X, such as oil whirl, oil whip, and modulated frequencies occur in Waterfall diagram. Additionally, the influences of the surface roughness and oil characteristics on the rotor behavior, friction, and wear are discussed. This book is written by an industrial R&D expert with many years of experience in the automotive and turbocharger industries. The all-in-one book of turbochargers is intended for scientific and engineering researchers, practitioners working in the rotordynamics field of automotive turbochargers, and graduate students in applied physics and mechanical engineering.
