非线性系统及其主要研究方法

A brief introduction to the nonlinear system

非线性系统是近年来控制理论研究的重点和热点之一。本文首先简要地介绍了非线性系统及其主要特征。而后就非线性系统的主要研究方法从多方面进行了讨论和归纳。最后,文章还指出了非线性系统理论尚未解决的问题,并指出了其发展前景。

The nonlinear system is the important study on control theory in recent years. This article gives not only a brief introduction of the nonlinear system but its main characters, and then discusses and generalizes the main methods of study on nonlinear system in many aspects. At last ,the article points out some unresolved problems on nonlinear system theory, and discusses some trends of the nonlinear system.
