Multiple Model Adaptive Active Control of Noise in a Duct
덕트 잡음 제거를 위한 다중 모델 적응 능동 소음 제어
Abstract
Adaptive active attenuation of noise in a duct is considered. A duct is modelled when the acoustic feedback exists. The secondary path transfer function is estimated using multiple model approaches. An IIR structure is assumed for the control filter, and the recursive least mean squares algorithm is used to adjust the filter coefficients.
