提出了一种基于约束优化的反馈型有源噪声控制滤波器的有效设计方法。所设计的滤波器在满足多个约束条件的同时，使给定标称对象的误差信号方差最小。通过采用频率翘曲技术，所设计的低阶滤波器达到了与传统高阶滤波器相似的性能，并具有鲁棒稳定性。实验结果验证了该方法的有效性。
This paper presents an efficient method of designing the feedback active noise control (ANC) filter based on a constrained optimization. The designed filter minimizes the variance of the error signal for a given nominal plant, while satisfying multiple constraints. By applying the frequency-warping technique, the designed low-order filter achieves similar performance to the conventional high-order filters and shows robust stability. Experimental results verify the efficiency of the proposed method.
