Active Vibration Control Systems in the Frequency and Sub-Band Domain

Active noise and vibration control has been the
subject of intense study in the last two decades.
Adaptive filtering plays a key role in the successful
applications of active noise and vibration control
systems. Some challenges facing adaptive filter
design is how to increase the convergence rate of
adaptive filtering and how to trade off the active
control performance from the various frequency
sub-bands. This book tackles these challenges by
implementing the adaptive filtering algorithm in the
frequency and sub-band domains. Specifically, this
book presents a new sub-band adaptive filter
architecture without a signal path delay and derives
the associated adaptive algorithm. The discussed
algorithms are applied to actively reduce the
vibration of a hard disk drive. Real time and
simulation results are provided throughout the book
accompanying the algorithm discussion. It not only
serves as an introductory text for active noise and
vibration control system, but as a practical
reference for developing adaptive algorithm in the
frequency and sub-band domains.
