피이드포워드와 피이드백 기법을 이용한 소음제어 알고리즘에 관한 연구

Abstract

In this study, we investigate the possibility to combine two active noise control(ANC) schemes, feedforward and feedback. When the source of noise is well identified and measureable, we can use feedforward scheme such as Flitered-X LMS algorithm using this information as reference. If reference is not accessible, we can use feedback scheme. For ANC of automobile, reference signal for feedforward scheme can be vibration of engine, vibration from the road.
