基于DSP的自适应主动噪声控制系统研究

Research on Self-adaptive Active Noice Control Based on DSP

介绍了自适应主动噪声控制技术的理论基础和结构组成、X-滤波最小均方算法、相关系统辨识以及在高速DSP芯片的高性能、自适应控制器对外界噪声有实时跟踪和自我参数优化的特点,整个系统具有良好的噪声抑制能力。

This article introduces the basic theory and structure of the self-adaptive active noise control,the filtered-X LMS algorithms, indentification of correlative system and their relizations in high-speed DSP chip. Because of the high performance of the programmable DSPchip,amd the characteristic of the real-time trace to the outside noise and the parameter self-optimization of the self-adaptive controller,the whole system has a good ability of noise control
