摘要
采用反馈FXLMS自适应控制算法,用TI公司的TMS320C30芯片作为控制器,并用TI公司的AD7874和AD7245分别作为模数和数模转换器,组成实时的噪声主动控制系统.应用于实际的通风管路噪声主动控制,获得良好效果.
In this paper the feedback FXLMS adaptive algorithm is applied for active noise control (ANC). The real\|time ANC system uses a TMS320C30 chip as a controller, and uses AD7874 and AD7245 as A/D and D/A converters. All these elements are the products of TI company. The system is applied on a practical ventiduct, and it is proven effective.
