The present research project intends to give a systematic study of the modern function theoretic approach, developed by the principal investigator, to sampled-data control systems. The emphasis here is upon the built-in intersample behavior in the design model based on the new notion called lifting, thereby differing greatly from the classical context. It aims at advancing1.frequency domain analysis/synthesis methods,2.introduction and introduction and computation of frequency response,3.H^* design methods4.algorithms for these computational issues.During the research term, we have successfully obtained the following results :1.introduction of the new notion of frequency response for sampled-data systems,2.relationship with the impulse modulation formula,3.its characterization via finite-dimensional eigenvalue problem,4.a solution to the H^* optimization problem,5.various computational algorithms,6.implementation as a CAD package.A promising sign of application toward signal processing has also been obtained. The interplay of the present research with this theme is undoubtedly the most logical, related and perhaps most fruitful target for the future.

本研究项目旨在对首席研究员开发的现代函数理论方法进行系统研究，用于采样数据控制系统。这里的重点是基于称为提升的新概念的设计模型中内置的样本间行为，从而与经典环境有很大不同。旨在推进1.频域分析/合成方法，2.频率响应的介绍和计算，3.H^*设计方法4.这些计算问题的算法。在研究期间，我们成功获得了以下成果： 1.介绍采样数据系统频率响应的新概念，2.与脉冲调制公式的关系，3.通过有限维特征值问题表征它，4.H^*优化的解决方案问题，5.各种计算算法，6.作为CAD软件包的实现。还获得了信号处理应用的有希望的迹象。目前的研究与这一主题的相互作用无疑是未来最合乎逻辑、最相关、或许也是最富有成果的目标。
