Extremum-seeking control tracks a varying maximum or minimum in a performance function such as output or cost. It attempts to determine the optimal performance of a control system as it operates, thereby reducing downtime and the need for system analysis. Extremum-seeking Control and Applications is divided into two parts. In the first, the authors review existing analog-optimization-based extremum-seeking control including gradient-, perturbation- and sliding-mode-based control designs. They then propose a novel numerical-optimization-based extremum-seeking control based on optimization algorithms and state regulation. This control design is developed for simple linear time-invariant systems and then extended for a class of feedback linearizable nonlinear systems. The two main optimization algorithms – line search and trust region methods – are analyzed for robustness. Finite-time and asymptotic state regulators are put forward for linear and nonlinear systems respectively. Further design flexibility is achieved using the robustness results of the optimization algorithms and the asymptotic state regulator by which existing nonlinear adaptive control techniques can be introduced for robust design. The approach used is easier to implement and tends to be more robust than those that use perturbation-based extremum-seeking control. The second part of the book deals with a variety of applications of extremum-seeking control: a comparative study of extremum-seeking control schemes in antilock braking system design; source seeking, formation control, collision and obstacle avoidance for groups of autonomous agents; mobile radar networks; and impedance matching. MATLAB®/Simulink® code which can be downloaded from www.springer.com/ISBN helps readers to reproduce the results presented in the text and gives them a head start for implementing the algorithms in their own applications. Extremum-seeking Control and Applications will interest academics and graduate students working in control, and industrial practitioners from a variety of backgrounds: systems, automotive, aerospace, communications, semiconductor and chemical 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.

The Symposium brought together many of the world’s experts in fluid mechanics, microfabrication and control theory to discover the synergy that can lead to real advances and perhaps find ways in which collaborative projects may proceed. The high profile meeting was attended by keynote speakers who are leaders in their fields. A key driver was the improvement in flow efficiency to reduce drag, and thereby emissions arising from transport. About 65 papers were presented.

The physical framework used to describe the various conversions is endoreversible thermodynamics, a subset of irreversible thermodynamics. Thermodynamics of Solar Energy Conversion provides an excellent generalized introduction into principles of solar energy conversion for everybody knowing some basics of university mathematics. Described are situations which are not in equilibrium and in which entropy is continuously created, but which are nevertheless stationary. In dealing with endoreversible thermodynamics, the given information in this book enables the reader to calculate the explicit values for a broad class of processes. It is demonstrated that solar energy conversion is a process particularly suited to being described in this way. "De Vos is a wonderful storyteller" —Prof. Dr. B. Andresen
