一种应对窄带非线性主动噪声控制的混合结构
A Novel Hybrid Structure for Narrowband Nonlinear Active Noise Control
摘要
Abstract
Analyzing the primary noise of an ANC system which contains narrowband reference signal,nonlinear primary path and non-minimum phase secondary path,and exploring the feedback structure based on FIR filter and the feedforward structure based on FLANN filter.By discussing the advantage and the disadvantage of these two structures,we proposed a new hybrid structure in this paper.Proposed FLANN-FIR structure composites the advantages of feedforward and feedback structures,not only the predictable noise can be reduced,but also the unpredictable noise can still be suppressed.Simulations under the cases of different signal noise ratio and different nonlinear primary path demonstrate that proposed hybrid structure performs best on the convergence rate and steady-state property.关键词
