摘要
有源消声是一种有效的低频噪声控制方法，由于空间有源消声过程具有时变性和非线性，传统的自适应算法不能进行很有效的控制。本文采用智能模糊控制策略，建立了基于智能模糊控制策略的有源消声系统，通过实验与传统自适应控制算法的消声效果作对比分析，证明智能模糊控制器不但控制速度快，易于实现，而且消声效果明显优于后者，具有较大的应用推广价值。
Active noise control is an effective method of noise control for low frequencies.The process of active noise control in space is time variable and nonlinear so that traditional adaptive algorithms can not work very effectively.In this paper,the intelligent fuzzy control tactics are adopted and an active noise control system is established based on these tactics.The comparative analysis of the experimental results of adopting traditional adaptive controller with the intelligent fuzzy controller shows that the intelligent fuzzy controller can be realized easily and performed fast,and the performance of noise reduction is better than conventional technique.The method is worthy to be spread and applied.
