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

The book "Active Vibration Control Systems in the Frequency and Sub-Band Domain" by Longji Wang offers a comprehensive analysis and innovative approaches to active noise and vibration control. Over the past two decades, this research field has developed intensively, with adaptive filtering techniques playing a central role. The work addresses specific challenges in the design of adaptive filters, particularly the increase of convergence rates and the optimization of active control performance across various frequency sub-bands. By implementing a novel sub-band adaptive filter architecture without signal path delay, an advanced adaptive algorithm is derived. The algorithms presented in the book are applied to the active reduction of vibrations in hard disk drives. Additionally, both real-time and simulation results are presented to support the theoretical concepts. This book serves not only as an introduction to active noise and vibration control but also as a practical reference for the development of adaptive algorithms in frequency and sub-band domains.
