Development and convergence analysis of new least-mean-square-based algorithm equipped with exponential-decay step size and disturbance compensation foractive noise control
收藏 引用
INTERNATIONAL JOURNAL OF ADAPTIVE CONTROL AND SIGNAL PROCESSING 2013年 第8期27卷 651-666页
作者: Lin, Jong-Yih Ho, Chia-Ying Natl Chung Hsing Univ Dept Mech Engn Taichung 40227 Taiwan
In real-world active noise control (ANC) applications, disturbance can be picked up by error sensors and significantly degrade the steady-state ANC performance. This study proposes two techniques in combination with a... 详细信息

JOURNAL OF THE ACOUSTICAL SOCIETY OF AMERICA 2008年 第6期123卷 4238-4249页
作者: Thomas, Jared K. Lovstedt, Stephan P. Blotter, Jonathan D. Sommerfeldt, Scott D. Brigham Young Univ Dept Mech Engn Provo UT 84602 USA Brigham Young Univ Dept Phys & Astron Provo UT 84602 USA
The FXlms algorithm, which is extensively used in active noise control, exhibits frequency dependent convergence behavior. This leads to degraded performance for time-varying and multiple frequency signals. A new algo... 详细信息

Increased disturbance rejection in magnetic disk drives by acceleration feedforward control and parameter adaptation
收藏 引用
CONTROL ENGINEERING PRACTICE 1997年 第6期5卷 741-751页
作者: White, MT Tomizuka, M Department of Mechanical Engineering University of California Berkeley CA 94720-1740 USA
As the density of data on magnetic disk drives increases, so does the need for more precise position control of the read/write head, especially in the presence of internal and external disturbances. This is achieved b... 详细信息
