dc.description.abstract在實際主動噪音控制的應用中,存在著與參考訊號不相關的干擾訊號(不相關音源),它會被誤差麥克風量測到,因而包含於誤差訊號中。當干擾隨著誤差訊號進入到控制器時,會影響控制器的權重更新,並且會使得主動噪音控制的消音性能(包括消音速度及消音量)降低。為了解決不相關音源對主動噪音控制系統的影響,因此本文提出了一新型混合式主動噪音控制的方法,用來同時處理相關與不相關音源,並且使用指數遞減型步階,以進一步提升消音的速度及消音量,進而提升消音性能。由電腦模擬結果可知,使用本文所提出的方法於主動噪音控制系統上,可以有效改善系統的消音性能,成功消除相關與不相關音源。zh_TW
dc.description.abstractIn practical active noise control applications, disturbances uncorrelated with the reference signal exist and can be picked up by error microphone. The disturbance will affect weights update of the ANC controller and degrade ANC performance. In this study, a new hybrid ANC structure and an exponential decay step size are proposed to deal with the problem caused by the disturbance such that both the correlated and uncorrelated noises can be attenuate at the same time. Simulation results demonstrate that the proposed method can effectively eliminate the correlated and uncorrelated noise and improve ANC performance.en_US
