摘要
在多智能体主动噪声控制方法理论研究基础上,对封闭空腔内噪声进行主动噪声智能控制试验,搭建试验系统软硬件平台,以验证该方法的有效性。针对两阶结构模态所主导的双频噪声设计两个控制器智能体,并建立基于双智能体的主动噪声控制系统。试验结果表明该方法能够有效抑制封闭空腔内噪声,并分别在误差麦克风1和误差麦克风2处取得了14 dB和9 dB的降噪量。尽管针对的是双频噪声,但由于智能体的结构基本上相同,因此易于将系统扩展为多智能体控制系统,从而实现多频或宽带噪声控制。
Based on the theoretical research of the multi-intelligent body active noise control method, the active noise intelligent control experiment was carried out on the noise in the enclosed cavity and the software and hardware platform of the test system was built to verify the effectiveness of the method. The two controller agents were designed for the dual-frequency noise dominated by the two-order structural mode, and an active noise control system based on the dual-agents was established. The experimental results show that the method can effectively suppress the noise in the enclosed cavity, and the noise reduction of 14 dB and 9 dB is achieved at error microphone 1 and error microphone 2, respectively. Although it is aimed at dual-frequency noise, since the structure of the agent is basically the same, it is easy to extend the system to a multi-agent control system so as to achieve the multi-frequency or broadband noise control.
