- In conventional ANC (Active Noise Control), the secondary path is usually modeled by an FIR filter with many coefficients, which is not easy to the realization and application of ANC. 在自适应有源控制中,次级通路建模对控制器算法实现有着重要的影响。
- The feedforward structure is investigated and the simulating results show that this method controls the primary noise signal perfectly whether the secondary path is variable or not. 就前馈控制结构加以研究，仿真结果表明，该方法不仅在次路径固定不变时，使噪声信号得到明显衰减，并且在次路径发生改变时，依然能很好地控制噪声。
- Because of the special structure of smart rotor, the problem, online secondary path modeling, should be solved when adaptive filter is used to actively control the helicopter vibration. 出于智能旋翼结构的特殊性，在应用自适应滤波的方法进行主动控制时须解决次级通道在线建模问题。
