Reverse Engineering in Control Design proposes practical approaches to building a standard H-infinity problem taking into account an initial controller. Such approaches allow us to mix various control objectives and to initialize procedures for a fixed-structure controller design. They are based on the Observer-Based Realization (OBR) of controllers. The interest of OBR from the controller implementation point of view is detailed and highlighted in this book through academic examples. An open-source toolbox is available to implement these approaches in Matlab®. Throughout the book academic applications are proposed to illustrate the various basic principles. These applications have been chosen by the author for their pedagogic contents and demo files and embedded Matlab® functions can be downloaded so readers can run these illustrations on their personal computers. Contents 1. Observer-based Realization of a Given Controller. 2. Cross Standard Form and Reverse Engineering. 3. Reverse Engineering for Mechanical Systems. Appendix 1. A Preliminary Methodological Example. Appendix 2. Discrete-time Case. Appendix 3. Nominal State-feedback for Mechanical Systems. Appendix 4. Help of Matlab® Functions. About the Authors Daniel Alazard is Professor in System Dynamics and Control at Institut Supérieur de l'Aéronautique et de l’Espace (ISAE), Toulouse, France – SUPAERO Graduate Program. His main research interests concern robust control, flexible structure control and their applications to various aerospace systems.
Changes in the world energy context, the increasing awareness of the environmental stakes and the development of research on the production of second and third generation biofuels revealed a clear need to write a new book which updates and complements all technical, financial and environmental aspects of Les Biocarburants—État des lieux, perspectives et enjeux du développement (Biofuels—Current status, outlook and development stakes) published in 2006. This book provides a detailed state of the art of the first generation biofuel production technologies. It describes the new «second generation» pathways which use lignocellulosic biomass as raw material and are starting to find industrial applications, thereby reducing the competition between the food resource and the use of agricultural materials for energy purposes. It also provides a technical update on the algaeto-energy pathway (third generation) and the production of methane and hydrogen by biochemical pathways. The book arrives at exactly the right time to renew the interest in biofuels, including for air transport, and provide an insight on the technological research and development axes currently being investigated. It is intended for transport companies, refiners, forestry companies, the agricultural and agribusiness sectors as well as the public authorities, students, university teachers and researchers.

Although Germany was one of the principal colonising nations in Africa and today is the world’s second largest aid donor , there is no literature on the postcolonial condition of contemporary German development policy. This book explores German development endeavours by state institutions as well as NGOs, and provides evidence of development policy’s unacknowledged entanglement in colonial modes of thought and practice. It zooms in on concrete policies and practices in selected fields of intervention: development education and billboard advertising in Germany, and – taking Tanzania as a case in point – obstetric care and population control in the Global South. The analysis finds that disregarding colonial continuities means to perpetuate the inequalities and injustices that development policy claims to fight. This book argues that colonial power in global development needs to be understood as functioning through the transnational character of development policy at home and abroad.
Model-based Systems Architecting is a key tool for designing complex industrial systems. It is dedicated to the working systems architects, engineers and modelers, in order to help them master the complex integrated systems that they are dealing with in their day-to-day professional lives. It presents the CESAMES Systems Architecting Method (CESAM), a systems architecting and modeling framework which has been developed since 2003 in close interaction with many leading industrial companies, providing rigorous and unambiguous semantics for all classical systems architecture concepts. This approach is practically robust and easy-to-use: during the last decade, it was deployed in more than 2,000 real system development projects within the industry, and distributed to around 10,000 engineers around the globe.
