摘要
对无人机螺桨噪声的主动控制技术进行实验研究。针对某型国产无人机,通过对其发动机螺桨噪声的测量分析,设计并开发了一个四入二出的主动噪声控制系统。利用该系统,在实验室环境下分别对100 Hz单频正弦噪声、实际风扇噪声和实际录取的某型号无人机螺桨噪声进行了噪声控制实验,取得了较好的消声效果。
Studied on the experiments which use active noise control technology to control UAV （ unmanned aer- ial vehicle） propeller noise, a multi-channel adaptive active noise control system which has four inputs and two out- puts is designed from measurement and analysis of the engine propeller noise of a certain type domestic UAV. Ex- periments on 100 Hz single-frequency noise, actual fan noise and actual UAV propeller were carried out. The ex- periment results shown that the system can achieve a good noise control effect.
