Adaptive Partial Model Matching Control method based on model matching on frequency domain utilizes the knowledge of several frequency responses of the controlled plant at finite number of frequency points. Hence this design technique has had the possibility to design sound field control systems in the feedback form because the human auditory sense can also be characterized by frequency characteristics.Based on the above stated view point, we have obtained following results concerning the design of feedback adaptive active sound field control systems.(1)Sound field control based on partial model matching on frequency domainThe criterion of the choice of the ideal sound field model, number of matching frequencies, a range of matching frequency domain are investigated.(2)2-degree-of-freedom construction of the feedback active sound field control systemsIt is proposed to use different frequency controllers which correspond to different frequency regions by dividing the matching frequency domain into 2-parts. This method is effective for sound field system having complex frequency characteristics caused by nonlinearities.(3)Design of audio servo system(4)Development of adaptive control algorithms for nonlinear plants and adaptive vibration control systemBasic adaptive control algorithms and general active vibration control concepts have been investigated for future application.Above stated results has been presented several national and international conferences and submitted (and prepare to submit) to several Journals. Concerning the content (1), one of our graduate students (co-researcher) obtained the best presentation award for young researchers from SICE.

基于频域模型匹配的自适应部分模型匹配控制方法是利用被控对象在有限个频率点上的多个频率响应知识。由于人的听觉也可以通过频率特性来表征，因此这种设计技术有可能以反馈形式来设计声场控制系统。基于上述观点，我们得到了反馈自适应有源声场控制系统的设计结果。(1)基于频域部分模型匹配的声场控制，研究了理想声场模型的选择准则、匹配频率的个数、匹配频域的范围。(2)反馈式有源声场控制系统的二自由度构建，通过将匹配的频域划分为两部分，采用不同的频率控制器对应不同的频率区域。该方法对非线性引起的复杂频率特性声场系统是有效的。(3)音频伺服系统的设计(4)非线性对象的自适应控制算法和自适应振动控制系统的发展研究了基本的自适应控制算法和一般的主动振动控制概念，以供未来应用。上述结果已在多个国家和国际会议上发表，并已提交（并准备提交）至多个期刊。关于内容(1)，我们的一名研究生（合作研究员）获得了SICE青年研究人员最佳演讲奖。
