This book presents a detailed discussion of intelligent
techniques to measure the displacement of buildings when they are subjected to
vibration. It shows how these techniques are used to control active devices
that can reduce vibration 60–80% more effectively than widely used passive
anti-seismic systems.



After introducing various structural control devices and
building-modeling and active structural control methods, the authors propose
offset cancellation and high-pass filtering techniques to solve some common
problems of building-displacement measurement using accelerometers. The most
popular control algorithms in industrial settings, PD/PID controllers, are then
analyzed and then combined with fuzzy compensation. The stability of this
combination is proven with standard weight-training algorithms. These conditions
provide explicit methods for selecting PD/PID controllers. Finally, fuzzy-logic
and sliding-mode control are applied to the control of wind-induced vibration.
Themethods described are supported by reports of experimental studies on a
two-story building prototype.



This book is a
valuable resource for academic researchers interested in the effects of control
and mechatronic devices within buildings, or those studying the principles of
vibration reduction. Practicing engineers working on the design and
construction of any sort of high-rise or vulnerable building and concerned with
the effects of either wind or seismic disturbances benefit from the efficacy of
the methods proposed.
