PREFACEActive and passive vibration control of structures

form a topic ofvery actual interest in many different fields of engineering, for ex-ample in the automotive industry, in aerospace engineering (e.g. inlarge telescopes) and also in civil engineering. The material presentedin this book tries to fill gaps between structural mechanics, vibrationsand modern control theory. It also establishes links between the dif-ferent applications in structural control. In vibration control it is stillcommon practice to a large extent to regard the design of mechanicalstructures and their damping and control as different topics, whichoften are treated sequentially, with the design of the structure to becarried out first, followed later by designing the active and passivevibration control. Similarly, in the standard curricula at most uni-versities, the mechanical modelling and the design of structures aswell as their control are treated as separate subjects. This book in-tends to fill some of the gaps between these different issues.

Theintention is to give a solid foundation of the mechanical

modellingand the vibration control for discrete and continuous structures, withan emphasis on the interfaces of the different disciplines.This book was written accompanying the CISM Course no. 418entitled ‘Active and Passive Vibration Control of Structures’ held inUdine from May 27 to 31, 2013. Therefore it is directed to youngresearchers, to doctoral students and also to engineers working infields related to structures, vibrations and control.

A thorough introduction into the relevant theory

both of the me-chanical modelling as well as of the vibration control theory are pre-sented and the most important design goals are discussed. Variousstrategies for modelling complex mechanical structures are given andan introduction to active, passive and semi-active strategies for vi-bration control are discussed. In a number of examples from differentareas it is shown that a comprehensive approach, in which both themechanical design problem and the development of suitable controlsare considered simultaneously, can present substantial advantages.The organization of the book is as follows.Chapter I, byPeter Hagedorn(Technische Universit ̈at Darm-stadt, Germany), treats equations of motion for discrete and con-

tinuous mechanical systems laying

the foundation for the creation ofcontrol models.Chapter II, byGottfried Spelsberg-Korspeter(TechnischeUniversit ̈at Darmstadt, Germany), gives an introduction to varia-tional principles in mechanics and control relating to mechanical mod-elling and the development of control strategies.Chapter III, byAndre Preumont,David AlalufandRenaudBastaits(Universit ́e Libre de Bruxelles, Belgium), treat hybrid massdampers for mitigating the dynamic response of buildings.Chapter IV, byAndre PreumontandBilal Mokrani(Uni-versit ́e Libre de Bruxelles, Belgium), discuss the theory of electromag-netic and piezoelectric transducers and presents some applications instructural control.Chapter V, byRobert Skelton(University of California SanDiego, United States), focuses on structure and design of control sys-tems with an emphasis on the advantages of using matrix inequalities.

Chapter VI, byAdnan Akay(Bilkent University, Turkey)

andAntonio Carcaterra(University of Rome, Italy), address thephysics and modelling of structural damping which is extremely im-portant in almost every structural control problem.Chapter VII, byRainer Nordmann(Technische Universit ̈atDarmstadt, Germany), deals with active magnetic bearings, whichcan be used for control purposes in rotating machinery.Summarizing, the material presented in this book will offer a uni-fied view on active and passive control and the mechanical modellingof structures presented from the point of view of experienced research-ers with quite different perspectives.The authors want to express their gratitude for the support of theCISM organization, in particular to Professor Friedrich Pfeiffer forchairing the course in Udine, and to Carla Toros for her tremendoussupport in organizing it.The authors sincerely thank Manuel Eckstein, who carried themain burden of editing the manuscripts and coordinating the differ-ent chapters, as well to Eduard Heffel, Matthias Heymanns, HenningSpiegelberg and Andreas Wagner.
