中文摘要: 非光滑控制是非线性控制领域内一个重要研究方向,对其进一步的深入研究有助于发展非线性控制理论。近年来,该方向逐渐成为一大研究热点,理论与应用方面的研究均已取得可喜进展。但是,非光滑控制理论本身还存在许多没有解决的问题。本项目拟对其中若干关键问题展开深入的研究,主要内容包括:研究非线性约束系统的非光滑控制设计,包括非光滑状态、输出反馈控制设计;研究随机系统非光滑控制设计,包括一类随机非线性下三角系统、一类随机非线性级联系统以及一类不确定随机非线性上三角系统等不同情况;针对一类不确定非线性系统,研究基于采样的非光滑状态、输出反馈控制设计;研究上述控制算法在多智能体系统、多机器人编队控制系统以及DC-DC变换器等典型系统中的应用设计和实现。本项目的研究将进一步完善非光滑控制理论,并促进非光滑控制理论在实际工程系统中的应用,改善控制系统性能,产生直接或间接的经济效益。

英文摘要: Nonsmooth control is an important branch in nonlinear control field. Deeper researches on this branch will make contributions to the development of nonlinear control theory. In recent years, this branch has been paid considerable attentions. As a result, there are lots of satisfactory results on nonsmooth control theory and applications. However, there are still many open problems in this field. This project will still study several key problems of nonsmooth control for nonlinear systems. The contents of the project include the nonsmooth control problems on nonlinear constrained systems, including state feedback, state observer and output feedback control design; stochastic nonlinear systems including different cases on stochastic nonlinear lower-triangular systems, stochastic nonlinear cascaded systems, and uncertain stochastic nonlinear upper-triangular systems; sampled-data control of a class of uncertain nonlinear systems, including state feedback, state observer and output feedback control design; applications of the above designed control algorithms to classic systems like multi-agent systems, formation control of multiple vehicles, and DC-DC converters, etc. The research will advance the applications of nonsmooth control methods to nonlinear systems, improve the performance of practical control systems and bring direct or indirect economical benefits.
