燃料电池汽车空辅系统噪声有源控制技术

燃料电池汽车（FCV）的动力系统及噪声特性与传统汽车相比有着很大差异，其中空气辅助系统已成为主要的噪声源。虽然有源噪声控制（ANC）是近年来的研究热点；但是，由于噪声源与环境的时变性，对空辅系统的中低频段噪声更有效的对策是使用自适应有源噪声控制技术（AANC）。在归纳总结有源噪声控制技术的发展进程及基本原理的基础上，阐述近年来有源噪声控制的研究现状，并重点分析关注自适应算法的研究进展；由此对自适应有源噪声控制在燃料电池汽车空辅系统减振降噪方面的应用前景进行预测和展望。

Active Noise Control Technology of Air Auxiliary System in Fuel Cell Vehicles

The power system of Fuel Cell Vehicle (FCV) is quite different from traditional cars, which leads to great differences in noise sources between FCV and traditional vehicle. Air auxiliary system is one of the main noise sources of FCV. Active Noise Control (ANC) has become a research focus recent years. It has advantages to the traditional passive noise control in middle- and low- frequency noise control. Because of time variation of noise sources and environments, it is necessary to use Adaptive Active Noise Control (AANC) in middle- and low- frequency noise control of air auxiliary system in FCV. The developing progress of ANC technology was summarized. Based on the basic concept of ANC, ANC research in recent years was expatiated. And the research progress of adaptive algorithm was focused on. Finally, the prospect of ANNC application in the field of vibration and noise reduction of air auxiliary system in FCV was forecasted.
