IV Acknowledgement The work presented in this thesis was initiated by the German federation of industrial research associations (AiF) together with the German association of powertrain technology (FVA) and conducted during my doctoral studies at the Chair of Dynamics and Control at the University of Duisburg-Essen. First of all, I would like to thank my supervisor Univ.-Prof. Dr.-Ing. Dirk Söffker for his great support, encouragement, and help. Without him, this work would never initiate nor finish. I would also like to thank Prof. Dr.-Ing. Dieter Schramm for his effort being the co-reviewer for my thesis. This work was conducted in collaboration with the Chair of Energy Technology at the University of Duisburg-Essen and a great appreciation is given to rer.-nat. Prof. Angelika Heinzel, Dr.-Ing. Jürgen Roes, their technical support Jochen Bindemann, and especially my working partner Lars Wülbeck. I would like to thank all my long time working partners at the Chair of Dynamics and Control; Hammoud Al-Joummaa, Kai-Uwe Dettmann, Dennis Gamrad, Frank Heidtmann, Yan Liu, Matthias Marx, and Mahmud-Sami Saadawia for their help and support and our secretaries Yvonne Vengels and Doris Schleithoff for their help with the administration. I wish them all the best in their future work. I would also like to thank all students who I supervised in their project works, bachelor-, and master theses. This includes Nguyen Binh, André Heßling, Xinfeng Huang, Sebastian Krins, Bertrand Teck Ping Ng, Yew Kok Poong, Adalbert Rudnicki, Theresia Rusch, Tharsis Ghim Han Teoh, and Shen Wang. I wish them all good luck in their studies. Special thanks are given to my prior supervisor and mentor, Prof. Svante Gunnarsson at the Chair of Automatic Control at Linköping University in Sweden, for giving me the interest for control technique. Finally but mostly I would like to thank my brothers and sisters and especially my parents whom without their love and support I would never be able to conduct this work.
