The book reports on the latest theoretical and experimental findings in the field of active flow and combustion control, in the context of energy conversion for power and propulsion systems. It covers new developments in actuator technology and sensing, robust and optimal open- and closed-loop control, model reduction for control purposes, and unsteady turbine cooling and performance, among other relevant topics. Gathering contributions to the Active Flow and Combustion Control (AFCC 2021), held virtually on September 28-29, 2021, from the Technische Universitat Berlin, Germany, this book describes research that has been carried out within, and supported by, the collaborative research center SFB 1029 on "Substantial efficiency increase in gas turbines through direct use of coupled unsteady combustion and flow dynamics", and funded by the German Research Foundation (DFG). It highlights theoretical and practical aspects, and corresponding solutions, that are important for the development of future energy conversion systems, thus offering a timely guide for researchers and practitioners in the field of aeronautics, turbomachinery, control and combustion.

This book aims to develop systematic design methodologies to model-based nonlinear control of aeroengines, focusing on (1) modelling of aeroengine systems-both component-level and identification-based models will be extensively studied and compared; and (2) advanced nonlinear control designs-set-point control, transient control and limit-protection control approaches will all be investigated. The model-based design has been one of the pivotal technologies to advanced control and health management of propulsion systems. It can fulfil advanced designs such as fault-tolerant control, engine modes control and direct thrust control. As a consequence, model-based design has become an important research area in the field of aeroengines due to its theoretical interests and engineering significance. One of the central issues in model-based controls is the tackling of nonlinearities. There are publications concerning with either nonlinear modelling or nonlinear controls; yet, they are scattered throughout the literature. It is time to provide a comprehensive summary of model-based nonlinear controls. Consequently, a series of important results are obtained and a systematic design methodology is developed which provides consistently enhanced performance over a large flight/operational envelope, and it is thus expected to provide useful guidance to practical engineering in aeroengine industry and research.

Klassische Pkw werden gerne als technisches Kulturgut gesehen. Das ist mit ein Grund, weshalb die Zahl derer, die Young- und Oldtimerfahrzeuge technisch in fahrfertigen Zustand versetzen und darin halten, stetig steigt. Hierzu ist technisches Verständnis, wie ein einzelnes Erzeugnis oder ein gesamtes System funktioniert, eine große Hilfe.Das Buch „Klassische Ottomotorsteuerung“, basierend auf der zum Teil stark überarbeiteten und ergänzten Gelben Reihe von Bosch, greift auf 416 Seiten genau diesen Sachverhalt auf und erklärt in anschaulicher Weise die Grundlagen zu Ottomotoren, insbesondere die Themen Gemischaufbereitung und Zündung. Neben klassischen Vergasern und Zündsystemen werden auch sämtliche Jetronic-Systeme abgebildet. Ein Kapitel zur frühen Motronic, die Zündung und Gemischaufbereitung erstmals miteinander vereint, rundet das Gesamtbild ab.  Das Buch ist somit für technikaffine Besitzer von Young- und Oldtimerfahrzeugen ein enormer Wissensfundus, um die technischen Funktionen der historischen Technik besser verstehen zu können.
