摘　　要：窄带主动控制系统适用于控制低频谐波噪声。在实际应用中,由于原始噪声频率快速变化导致的参考信号失调问题会使窄带主动控制系统性能严重下降,而现有的频率估计算法往往难以兼顾跟踪实际频率的速度、精度与计算复杂度。本文提出一种Notch-HAQSE频率估计窄带主动控制算法,通过陷波滤波器与基于DFT系数的高精度单频估计算法(HAQSE)组合来提取参考传感器信号中任意数量的线谱频率成分,并合成参考信号送入控制器完成次级信号更新。仿真和试验结果表明,与现有的应用于主动控制的其他频率估计方法相比,提出的方法能准确识别和快速跟踪多个频率,并大幅度降低了计算复杂度,较好地解决了参考信号失配问题和多线谱振动噪声控制问题。The narrowband active control system is suitable for controlling low-frequency harmonic noise.In practical applications,the problem of reference signal mismatch caused by the rapid frequency changes of the original noise will seriously degrade the per-formance of the narrowband active control system.Existing frequency estimation algorithms often struggle to balance the speed,ac-curacy,and computational complexity required to track the actual frequency.This paper proposes a Notch-HAQSE frequency esti-mation algorithm for narrowband active control,which extracts any number of line spectrum frequency components from the refer-ence sensor signal by combining a notch filter with a high-precision single-frequency estimation algorithm based on DFT coeffi-cients(HAQSE).The synthesized reference signal is sent to the controller to complete secondary signal updating.Simulation and experimental results show that,compared with other frequency estimation methods used in active control,the proposed method ac-curately identifies and rapidly tracks multiple frequencies while significantly reducing computational complexity.It effectively ad-dresses the problem of reference signal mismatch and multi-line spectrum vibration noise control.
