一种信号综合自适应管道有源消声系统的研究

THE RESEARCH OF DUCT ACTIVE NOISE CONTROL

探讨采用信号综合自适应系统的超稳定设计法实现管道有源消声的方法，解决了自适应状态观测器的设计以及如何实现纯滞后系统的自适应控制问题，最后给出计算机仿真结果，从而验证了这种设计方法的可行性。

This paper discussed the asymptotic hyperstable adaptive design of signal-synthesis MRAS to realize a duct active noise control.It also resolved how to design an adaptive observer and how to manage the adaptive control of a pure delay system. In the end the results of computer simulations proved its feasibility of this design method.
