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. The methods 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.
