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. ***

9528363约翰逊我们提出了一个研究计划，以使用自适应识别和控制方法进行主动控制声学噪声（及其相关问题）。 激励的应用是在一维或管道噪声方案（例如加热，通风和空调或HVAC应用）中控制声噪声的控制，以及在三维或外壳风景中控制噪声的控制（例如，自动机动或直升机内部内部）。 在本研究计划中需要解决的开放问题（a）在存在固有的反馈循环中使用的自适应技术的系统稳定性分析，这些反馈循环是通过声学反馈引起的，而不是通过自适应控制理论和（b）在自适应档案理论和（b）自适应档案中尤其是在MIMO Encoples中的开发和有效实施的通常闭环控制配置。 该研究计划将阐明自适应控制理论和实践的相关方面，从而允许系统应用自适应技术。 该研究计划将与康涅狄格州东哈特福德联合技术研究中心的实验设施合作进行。预计由此合作组成的多学科团队将允许实现广泛的实践研究结果，并广泛传播，从而为教育和商业利益做出贡献。 ***
