This book presents a detailed discussion of intelligenttechniques to measure the displacement
of buildings when they are subjected tovibration. It shows how these techniques are used to
control active devicesthat can reduce vibration 60-80% more effectively than widely used
passiveanti-seismic systems.After introducing various structural control devices
andbuilding-modeling and active structural control methods the authors proposeoffset
cancellation and high-pass filtering techniques to solve some commonproblems of
building-displacement measurement using accelerometers. The mostpopular control algorithms in
industrial settings PD PID controllers are thenanalyzed and then combined with fuzzy
compensation. The stability of thiscombination is proven with standard weight-training
algorithms. These conditionsprovide explicit methods for selecting PD PID controllers. Finally
fuzzy-logicand sliding-mode control are applied to the control of wind-induced vibration.The
methods described are supported by reports of experimental studies on atwo-story building
prototype. This book is avaluable resource for academic researchers interested in the effects
of controland mechatronic devices within buildings or those studying the principles
ofvibration reduction. Practicing engineers working on the design andconstruction of any sort
of high-rise or vulnerable building and concerned withthe effects of either wind or seismic
disturbances benefit from the efficacy ofthe methods proposed.
