Multi-tonal feedback control with improved plant and frequency estimation
Multi-tonal feedback control with improved plant and frequency estimation
Active noise control' is a popular research field in
academia as'well as for commercial. purposes. Despite
this little progress was made to search new and effective
controller tuning'methods. In this paper we present an
alternative tuning algorithm for multi-tone disturbance
signals to the widely used filtered,reference signal least
mean square: approach. Advantages of the newly developed
method allow faster convergence and a more
precise frequency estimation. Its control behaviour was
examined in simulations. The identified dynamics of a
laboratory duct system were used'for the control path.
The disturbance signal consisted of three non-harmonic
tones, with frequencies which cannot be represented
using integer numbers. The frequencies were identified
using a frequency estimation scheme. An output
attenuation of 18 dB was achieved.

Abstract
Active noise control' is a popular research field in
academia as'well as for commercial. purposes. Despite
this little progress was made to search new and effective
controller tuning'methods. In this paper we present an
alternative tuning algorithm for multi-tone disturbance
signals to the widely used filtered,reference signal least
mean square: approach. Advantages of the newly developed
method allow faster convergence and a more
precise frequency estimation. Its control behaviour was
examined in simulations. The identified dynamics of a
laboratory duct system were used'for the control path.
The disturbance signal consisted of three non-harmonic
tones, with frequencies which cannot be represented
using integer numbers. The frequencies were identified
using a frequency estimation scheme. An output
attenuation of 18 dB was achieved.
