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。

In order to reasonably choose active noise control (ANC) algorithm in practical engineering, the performances of three typical ANC algorithms, FxLMS, GSFxAP and FsLMS, were investigated in different conditions by simulations and experiments. The conditions of application of the algorithms were also studied. It was concluded that if the secondary path is linear and the convergence speed does not need to be very high, FxLMS algorithm is the best choice;if the noise to be controlled (i.e. the primary noise) is non-stationary or the convergence speed needs to be very high, GSFxAP algorithm is a suitable choice;if the correlation between the primary noise and reference signal is weak, FsLMS algorithm is the reasonable choice. This conclusion provides a theoretical guide for the choice of ANC algorithm in practical engineering.
