Technology of Semiactive Devices and Applications in Vibration Mitigation (PDF)

Researchers have studied many methods of using active and passive
control devices for absorbing vibratory energy. Active devices,
while providing significant reductions in structural motion,
typically require large (and often multiply-redundant) power
sources, and thereby raise concerns about stability. Passive
devices are fixed and cannot be modified based on information of
excitation or structural response. Semiactive devices on the other
hand can provide significant vibration reductions comparable to
those of active devices but with substantially reduced power
requirements and in a stable manner.

Technology of Semiactive Devices and Applications in
Vibration Mitigation presents the most up-to-date research into
semiactive control systems and illustrates case studies showing
their implementation and effectiveness in mitigating vibration. The
material is presented in a way that people not familiar with
control or structural dynamics can easily understand.

Connecting structural dynamics with control, this book:

* Provides a history of semiactive control and a bibliographic
review of the most common semiactive control strategies.

* Presents state-of-the-art semiactive control systems and
illustrates several case studies showing their implementation and
effectiveness to mitigate vibration.

* Illustrates applications related to noise attenuation, wind
vibration damping and earthquake effects mitigation amongst
others.

* Offers a detailed comparison between collocated and
non-collocated systems.

* Formulates the design concepts and control algorithms in simple
and readable language.

* Includes an appendix that contains critical considerations
about semiactive devices and methods of evaluation of the original
damping of a structure.

Technology of Semiactive Devices and Applications in
Vibration Mitigation is a must-have resource for researchers,
practitioners and design engineers working in civil, automotive and
mechanical engineering. In addition it is undoubtedly the key
reference for all postgraduate students studying in the field.
