应用有源噪声控制（ＡＮＣ）理论，在比较反馈控制结构（ＦＢＣＳ）和前馈控制结构（ＦＦＣＳ）后，提出采用模型参考自适应中的ＭＲＡＳ超稳定性设计方法，构造一种反馈结构自适应降噪的实施方案。实验表明，消声效果明显。
Applying the theory of active noise control (ANC), after comparing the FBCS with the FFCS, the MRAS superstability design method in model reference adaptive is proposed to construct a feedback structure adaptive Noise reduction implementation plan. Experiments show that noise reduction effect is obvious.
