우리는 사전 역 능동 잡음 제어(PIANC) 시스템을 위한 보조 잡음 전력 스케줄링 방법을 제안한다. 기존 방법에서는 필터링된 x 최소 평균 제곱(FxLMS) 알고리즘을 사용하기 때문에 보조 잡음의 전력을 줄일 수 없습니다. 우리는 이 문제를 해결하기 위해 PIANC 시스템의 전력 스케줄링 방법을 개발했습니다. PIANC 시스템은 지연된 입력 신호를 제어 필터로 사용하므로 제안하는 방법은 음향 경로가 변동하더라도 안정성을 제공한다. 제안된 방법은 XNUMX차 경로 모델링 상태에 따라 보조 잡음 이득을 제어한다. 제안된 방법은 XNUMX차 경로 모델링 오류 신호의 전력 변화에 따라 이 상태를 결정합니다. 따라서 제안하는 방법은 보조 잡음의 전력 스케줄링을 변경한다. 제안하는 방법은 적응 알고리즘이 충분히 수렴하지 못하는 경우 보조 잡음을 주입한다. 그러나 적응 알고리즘이 충분히 수렴되면 보조 잡음이 중지됩니다. 따라서 제안하는 방법은 잡음 감소 성능을 향상시킨다.

Abstract: We propose an auxiliary-noise power-scheduling method for a pre-inverse active noise control (PIANC) system. Conventional methods cannot reduce the power of auxiliary-noise due to the use of the filtered-x least mean square (FxLMS) algorithm. We developed our power-scheduling method for a PIANC system to solve this problem. Since a PIANC system uses a delayed input signal for a control filter, the proposed method delivers stability even if the acoustic path fluctuates. The proposed method also controls the gain of the auxiliary-noise based on the secondary-path-modeling state. The proposed method determines this state by the variation in the power of the secondary-path-modeling-error signal. Thus, the proposed method changes the power-scheduling of the auxiliary-noise. When the adaptive algorithm does not sufficiently converge, the proposed method injects auxiliary-noise. However, auxiliary-noise stops when the adaptive algorithm sufficiently converges. Therefore, the proposed method improves noise reduction performance.
