"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.

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.

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 codypower.com). 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.

This book thoroughly covers the fundamentals of the QFT robust control, as well as practical control solutions, for unstable, time-delay, non-minimum phase or distributed parameter systems, plants with large model uncertainty, high-performance specifications, nonlinear components, multi-input multi-output characteristics or asymmetric topologies. The reader will discover practical applications through a collection of fifty successful, real world case studies and projects, in which the author has been involved during the last twenty-five years, including commercial wind turbines, wastewater treatment plants, power systems, satellites with flexible appendages, spacecraft, large radio telescopes, and industrial manufacturing systems. Furthermore, the book presents problems and projects with the popular QFT Control Toolbox (QFTCT) for MATLAB, which was developed by the author.

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
