Multivariable Feedback Control: Analysis and Design, Second Edition presents a rigorous, yet easily readable, introduction to the analysis and design of robust multivariable control systems. Focusing on practical feedback control and not on system theory in general, this book provides the reader with insights into the opportunities and limitations of feedback control. Taking into account the latest developments in the field, this fully revised and updated second edition: * features a new chapter devoted to the use of linear matrix inequalities (LMIs); * presents current results on fundamental performance limitations introduced by RHP-poles and RHP-zeros; * introduces updated material on the selection of controlled variables and self-optimizing control; * provides simple IMC tuning rules for PID control; * covers additional material including unstable plants, the feedback amplifier, the lower gain margin and a clear strategy for incorporating integral action into LQG control; * includes numerous worked examples, exercises and case studies, which make frequent use of Matlab and the new Robust Control toolbox. Multivariable Feedback Control: Analysis and Design, Second Edition is an excellent resource for advanced undergraduate and graduate courses studying multivariable control. It is also an invaluable tool for engineers who want to understand multivariable control, its limitations, and how it can be applied in practice. The analysis techniques and the material on control structure design should prove very useful in the new emerging area of systems biology. Reviews of the first edition: "Being rich in insights and practical tips on controller design, the book should also prove to be very beneficial to industrial control engineers, both as a reference book and as an educational tool." Applied Mechanics Reviews "In summary, this book can be strongly recommended not only as a basic text in multivariable control techniques for graduate and undergraduate students, but also as a valuable source of information for control engineers."

Genre: Science

"Linear and Nonlinear Multivariable Feedback Control presents a highly original, unified control theory of both linear and nonlinear multivariable (also known as multi-input multi-output (MIMO)) feedback systems as a straightforward extension of classical control theory. It shows how the classical engineering methods look in the multidimensional case and how practising engineers or researchers can apply them to the analysis and design of linear and nonlinear MIMO systems."--BOOK JACKET.

Optimale lineare Regelung

Author: Sebastian Engell
Publisher: Springer-Verlag
ISBN: 9783642834431
Release Date: 2013-03-08
Genre: Mathematics

Gegenstand des Buches ist die Bestimmung der bestmöglichen erreichbaren Regelgüte in linearen zeitinvarianten Regelkreisen. Hierbei werden keine Einschränkungen bezüglich der Struktur der Regelstrecke oder der Regler gemacht. Ausgangspunkt der Untersuchungen ist eine praxisnahe Spezifikation des gewünschten Regelkreisverhaltens, die Stabilität, gutes Folgeverhalten und Robustheit sicherstellt, in Form von Schranken für bestimmte Frequenzgänge des geschlossenen Regelkreises. Es wird dann schrittweise die mathematische Theorie entwickelt, mit der sich die Einhaltbarkeit solcher Spezifikationen für ein gegebenes Streckenmodell überprüfen und die optimale Regelgüte ermitteln läßt. Dies geschieht zunächst ausführlich für zeitkontinuierliche Eingrößenregelkreise. Mit Hilfe einer neu entwickelten Methode zur numerischen Auswertung der resultierenden Bedingungen wurden erstmals für die wichtigsten Streckentypen Diagramme berechnet, die exakt die notwendigen Kompromisse bei der Regelkreisspezifikation angeben. Unter Benutzung der w-Transformation werden die Ergebnisse auf zeitdiskrete Regelungen übertragen. Eine knappe Darstellung der Verallgemeinerung der Methodik auf Mehrgrößenregelungen bildet den Abschluß des Buches. Da die erforderliche Robustheit des Regelkreises Bestandteil der Spezifikation ist, liefert die dargestellte Theorie auch eine Aussage darüber, ob für ein konkretes Problem festeingestellte lineare Regler ausreichend sind, oder ob zu komplexeren Regelungen (nicht-linear, schaltend, adaptiv) übergegangen werden muß, um die geforderte Regelgüte zu erreichen.

Wind Energy Systems

ISBN: 9781466552241
Release Date: 2012-02-02
Genre: Technology & Engineering

Presenting the latest developments in the field, Wind Energy Systems: Control Engineering Design offers a novel take on advanced control engineering design techniques for wind turbine applications. The book introduces concurrent quantitative engineering techniques for the design of highly efficient and reliable controllers, which can be used to solve the most critical problems of multi-megawatt wind energy systems. This book is based on the authors’ experience during the last two decades designing commercial multi-megawatt wind turbines and control systems for industry leaders, including NASA and the European Space Agency. This work is their response to the urgent need for a truly reliable concurrent engineering methodology for the design of advanced control systems. Outlining a roadmap for such a coordinated architecture, the authors consider the links between all aspects of a multi-megawatt wind energy project, in which the wind turbine and the control system must be cooperatively designed to achieve an optimized, reliable, and successful system. Look inside for information about the QFT Control Toolbox for Matlab, the software developed by the author to facilitate the QFT robust control design (see also the link at The textbook’s big-picture insights can help students and practicing engineers control and optimize a wind energy system, in which large, flexible, aerodynamic structures are connected to a demanding variable electrical grid and work automatically under very turbulent and unpredictable environmental conditions. The book covers topics including robust QFT control, aerodynamics, mechanical and electrical dynamic modeling, economics, reliability, and efficiency. It also addresses standards, certification, implementation, grid integration, and power quality, as well as environmental and maintenance issues. To reinforce understanding, the authors present real examples of experimentation with commercial multi-megawatt direct-drive wind turbines, as well as on-shore, offshore, floating, and airborne wind turbine applications. They also offer a unique in-depth exploration of the quantitative feedback theory (QFT)—a proven, successful robust control technique for real-world applications—as well as advanced switching control techniques that help engineers exceed classical linear limitations.

Robust Multivariable Control of Aerospace Systems

Release Date: 2002
Genre: Science

Classical design and analysis techniques, many of which date back to the 1950's, are still predominantly used in the aerospace industry for the design and analysis of automatic flight control and aero-engine control systems. The continued success and popularity of these techniques is particularly impressive considering the radical advances in aircraft and spacecraft design and avionics technology made over this period. Clearly, an understanding of both the advantages and limitations of these methods is essential in order to properly evaluate the likely usefulness of more modern techniques for the design and analysis of aerospace control systems. One of the themes of this book is that the multivariable robust control methods it describes are logical and natural extensions of the more classical methods, and not replacements for them. It is assumed that readers of this publication are already familiar with classical flight control techniques. Emphasis is on the philosophy, advantages and limitations of the classical approach to flight control system design and analysis. Abstracted in Inspec

Publisher: John Wiley & Sons
ISBN: 9781118822333
Release Date: 2014-10-27
Genre: Technology & Engineering

Most existing robust design books address design for static systems, or achieve robust design from experimental data via the Taguchi method. Little work considers model information for robust design particularly for the dynamic system. This book covers robust design for both static and dynamic systems using the nominal model information or the hybrid model/data information, and also integrates design with control under a large operating region. This design can handle strong nonlinearity and more uncertainties from model and parameters.

Robuste Regelung

Author: Jürgen Ackermann
Publisher: Springer-Verlag
ISBN: 9783662097779
Release Date: 2013-03-09
Genre: Technology & Engineering

Robuste Regelung stellt einen für die praktische Umsetzung wichtigen Aspekt der Regelungstheorie dar. Sie gibt Auskunft, ob die Einschwingvorgänge linearer Regelsysteme rasch abklingen. Dies ist wichtig bei realen Systemen, bei denen sich starke Änderungen der Betriebsbedingungen einstellen, in der Praxis z.B. bei einem Kran mit variabler Seillänge oder Lastmasse, aber auch bei einem Flugzeug, das mit verschiedenen Geschwindigkeiten in verschiedenen Höhen fliegt. Robuste Regelung von Jürgen Ackermann liefert den neuesten Stand der Verfahren zur Robustheitsanalyse. Es werden Entwurfswerkzeuge (Parameterraum-Verfahren, Gütevektor-Optimierung) vorgestellt und auf die Regelung praktischer mechanischer Systeme aus Automobil- und Luftfahrttechnik angewendet. Angesprochen sind in erster Linie Ingenieure der Elektrotechnik und des Maschinenbaus.
