摘要

摘要: 传统窄带主动噪声控制系统中，各窄带噪声分量由各控制器并行处理，而相应的控制系数却仍由系统的整体残余误差进行更新。这导致各控制器之间相互影响，从而降低了系统的收敛速度。为保证各控制器单独利用自身的残余误差来更新控制系数，实现残余误差信号的频率分量分离，该文提出一种基于泄漏残余误差分离器的窄带主动噪声控制系统，并对新系统进行初步统计分析。理论分析、仿真及实验表明，这种引入泄漏因子的残余误差分离器，在不牺牲稳态性能情况下，提升了系统的鲁棒性和收敛性。

Abstract: In a conventional narrowband active noise control system, each narrowband component is cancelled separately, but each control coefficient is still updated by the overall residual error of the system. This leads to the interferences among the controllers, thus reducing the convergence rate of the system. In order to ensure that each controller uses its own residual error to update the control coefficient and to separate frequency components from residual error signals, a complete narrowband active noise control system based on leaky residual error separator is proposed, and the corresponding preliminary statistical analysis on the new system is derived. Extensive simulations and experimental results as well as theoretical analysis demonstrate that the robustness and convergence performances can be improved without increasing the residual noise in the steady state by using the residual error separator that introduces the leakage factor.
