中文摘要: 本项目旨在应用模糊系统理论,结合自适应反步递推(Backstepping)技术、随机小增益定理和鲁棒控制理论,研究随机非线性系统的分析与控制问题,发展模糊控制理论和设计方法。主要研究下述问题:1.针对一类不具有下三角结构的随机非线性系统,寻找系统函数可实施变量分离的条件和方法,进而利用自适应模糊控制技术为解决该类系统的输出跟踪、扰动解藕等控制问题提供新的思路和方法;2.研究含有输入死区(或饱和)的随机非线性系统的自适应模糊控制问题,在死区(或饱和)参数未知的条件下,尝试设计出新的自适应模糊控制方案。该项目的成功研究对发展随机非线性系统自适应模糊控制理论具有重要的学术价值,为研究实际工程中的控制问题提供理论依据和设计方法。

英文摘要: This project will utilize fuzzy system theory, adaptive backstepping technology, stochastic small-gain theorem and robust control theory to investigate the problem of analysis and control design for stochastic nonlinear systems and develop fuzzy control theory and design method. The main considered problems are as follows: 1. For a class of stochastic nonlinear systems with no lower triangular structure, we firstly investigate the conditions and methods for separation of variables to the system function, then provide new ideas and methods for dealing with the problems of output tracking and disturbance decoupling based on adaptive fuzzy control apprach; 2. We focus on the problem of adaptive fuzzy control for stochastic nonlinear systems with input dead zone (or saturation), and manage to design a novel adaptive fuzzy control scheme while the parameters of dead zone (or saturation) are unknown. Success of this project will have important academic value to the development of adaptive fuzzy control theory for stochastic nonlinear systems, and provide theoretical basis and design method for the control problems in practical engineering.
