摘　　要：有源消声采用自适应控制技术已经成为发展趋势，但是由于自适应控制理论发展迅速，一些较为成熟的、新的设计方法尚未应用到有源消声中．为了将这两种技术更紧密地结合起来，本文首先介绍了自适应控制领域内得以公认的模型参考自适应系统（ＭＲＡＳ）的超稳定设计方法及其简化工程设计方法，其次总结了自适应有源消声的理论进展和应用成果，最终提出采用ＭＲＡＳ的设计方法实现有源消声的新方案，为自适应有源消声的应用开辟了新的途径．Using adaptive control has been become a tendency towards active noise control. But the progress of adaptive control has been made so great that some mature and new design methods have not been applied in active noise contiol. In order to combine the be kind of technic compactly, the paper is introduced the asymptotic hyperstable method of MRAS and the MRAS engineering design method which have been accepted by public And then it summarizes the latest developments in theories and applications. In the end a new method of using MRAS design method to realize active noise control is presented and it also opens a new gate to the applications of adaptive adive noise control.
