GOALI:Adaptive Active Noise Control: Stability Analysis, Algorithm Development, and Efficient Implementation

我们提出了一个使用自适应识别和控制方法主动控制噪声（及相关问题）的研究计划。激励应用是在一维或管道噪声情况下的噪声控制（例如加热，通风和空调或HVAC应用）以及在三维或封闭情况下的噪声控制（例如汽车或直升机内部）。本研究计划中要解决的开放性问题涉及(a)在存在固有反馈回路的情况下使用的自适应技术的系统稳定性分析，这些应用是由声学反馈引起的，而不是由自适应控制理论中假设的通常闭环控制配置引起的；(b)自适应滤波器的开发和有效实现，特别是在MIMO外壳问题中。该研究计划将阐明自适应控制理论和实践的相关方面，从而允许自适应技术的系统应用。该研究项目将与位于康涅狄格州东哈特福德的联合技术研究中心的实验设施合作进行。预期通过这种合作而组成的多学科小组将能够取得广泛和实际的研究成果并广泛传播，从而对教育和商业利益作出贡献。＊＊＊

9528363 Johnson We propose a research program in the active control of acoustic noise (and related problems) using adaptive identification and control methodologies. The motivating applications are the control of acoustic noise in a one dimensional or duct noise scenario (e.g. heating, ventilation and air conditioning or HVAC applications) as well as the control of noise in a three dimensional or enclosure scenario (e.g. automobile or helicopter interiors). Open problems to be addressed in this research program concern (a) the systematic stability analysis of adaptive techniques used in the presence of intrinsic feedback loops which are caused in these applications by acoustic feedback and not by the usual closed loop control configurations assumed in adaptive control theory and (b) the development and efficient implementation of adaptive filters especially in the MIMO enclosure problem. The research program will clarify the pertinent aspects of adaptive control theory and practice and thus allow the systematic application of adaptive techniques. The research program will be conducted in collaboration with and will utilize experimental facilities of the United Technologies Research Center in East Hartford, CT. It is expected that the multidisciplinary team thus assembled by this collaboration will allow for wide-ranging and practical research results to be achieved and broadly disseminated thus making contributions to both education and commercial interests. ***
