摘要： 设计了FxLMS、GSFxAP、FsLMS等三类有源控制算法的仿真实验和消声室实验，分析了算法性能，对算法的适用条件进行深入研究。结果表明：当次级通路为线性通路时，在实际应用对收敛速度要求不高的情况下，选择FxLMS算法的性能代价比最高。如果欲控制的噪声为非平稳噪声或对算法收敛速度要求较高，GSFxAP算法是最优选择。如果参考信号与初级信号相关性差，选用FsLMS算法最为合适。上述结论为实际工程中有源控制算法的选择提供了理论依据。

Abstract: In order to investigate how to choose active noise control algorithm in practical engineering, the performances of typical ANC algorithms are investigated in different conditions by simulations and experiments. The conditions of application of the algorithms are also studied. It is concluded that if the secondary path is linear and the requirement of the convergence speed is not strictly demanded，FxLMS algorithm is the best choice. If the noise to be actively controlled (i.e. the primary noise) is non-stationary or the requirement of convergence speed is strictly demanded, GSFxAP algorithm is a suitable choice. If the correlation between the primary noise and reference signal is poor, FsLMS algorithm is the choice. It provides a theoretical guide for the choice of active control algorithm in practical engineering.
