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.
