With Active Control of Structures, two global pioneerspresent the state-of-the-art in the theory, design and applicationof active vibration control. As the demand for high performancestructural systems increases, so will the demand for informationand innovation in structural vibration control; this book providesan effective treatise of the subject that will meet thisrequirement. The authors introduce active vibration control throughthe use of smart materials and structures, semi-active controldevices and a variety of feedback options; they then discuss topicsincluding methods and devices in civil structures, modal analysis,active control of high-rise buildings and bridge towers, activetendon control of cable structures, and active and semi-activeisolation in mechanical structures.

Active Control of Structures:

  • Discusses new types of vibration control methods and devices,including the newly developed reduced-order physical modellingmethod for structural control;
  • Introduces triple high-rise buildings connected by activecontrol bridges as devised by Professor Seto;
  • Offers a design strategy from modelling to controller designfor flexible structures;
  • Makes prolific use of practical examples and figures todescribe the topics and technology in an intelligible manner.

About the author (2008)

Andre Preumont was born in 1951. He obtained his PhD fromthe University of Liege (Belgium) in 1981 while he was working inearthquake engineering at Belgonucleaire. In 1985-6, he wasvisiting professor in the Aerospace and Ocean Engineeringdepartment at Virginia Tech (USA). He was appointed tot eh chair ofMechanical Engineering and Robotics of ULB (Universite Libre deBruxelles) in 1987. He created the Active Structures Laboratory in1995. He is also part-time professor at the University of Liege. Heis the author of several books on active vibration control andrandom vibration. His current research interests are inmechatronics, active vibration control, adaptive optics andprecision engineering. He has had visiting positions at UTC,Compiegne and INSA-Lyon (France).

Kazuto Seto was born in 1938. He graduated from adoctoral course in Engineering at Tokyo Metropolitan University in1971 and received a Dr. Eng. degree from Tokyo MetropolitanUniversity in the Same Year. He worked as an associate professorand professor in the Department of Mechanical Engineering,NationalDefense Academy from 1973 until 1993. From 1993, he worked as aprofessor in the Department of Mechanical Engineering, NihonUniversity. He retired in 2007 and is now president ofSeto-Vibration Control Laboratory. He retired in 2007 and is nowpresident of Society of Mechanical Engineers (JSME) and a fellow ofIE Australia. He was given JSME Awards for his research in 1984 and1989, and the Dynamics, Measurement and Control Award from JSME in1994 and 1996. His research interests in the areas of structuralvibration control, system modeling and identification, motion andvibration control for multistructural systems with multi-controlledmodes.
