Formulation of control theory for nonlinear dynamics making full use of structural and quantitative information

技术正在向全局和微观对象发展。在20世纪下半叶，我们着眼于可以忽略多样性的规模，并以直线和统一（线性）的方式开发技术。技术革命的关键是解决各种各样的动态，既不是直线也不是均匀的（非线性）。为了改变控制工程中标准化过程中只关注定量值的趋势，本研究建立了非线性动力学稳定性理论的基本框架，使我们能够将定量和定性信息相结合。这个跨学科的工具帮助我们解决了重要的动力学设计问题，这些问题仍然没有解决。

Technologies are advancing toward global and micro objects. In the second half of the 20th century, we looked at sizes in which we could ignore diversity and develop technologies in a straight and uniform (linear) manner. The key to the technological revolution is to tackle an unlimited variety of dynamics which is neither straight nor uniform (nonlinear). To bring about a great change in control engineering whose recent trend has been to focus only on quantitative values in standardized process, this research has developed a fundamental framework for stability theory of nonlinear dynamics, which enables us to integrate quantitative and qualitative information. This interdisciplinary tool helps us solve important dynamics design problems which have remained unsolved.
