中文摘要: 随着科学实践和理论研究的深入,非线性微分包含控制系统正在成为不确定性控制系统研究的热点之一。本项目考虑鲁里叶型微分包含控制系统,其线性部分可以带参数,而其集合值函数是凸闭值或紧的,或满足极大单调性质。研究这类系统的输入-状态镇定和观测器等具有根本意义的控制系统设计问题。在镇定问题中,用Lyapunov 定理和控制Lyapunov 函数方法建立镇定条件,并进一步探究含有参数系统的镇定问题;提出降维观测器设计方法,应用自适应观测器设计理论,从输出方程估计出集合值函数的输出,从而按照通常方法设计观测器,由此建立微分包含系统观测器设计的新理论。

英文摘要: By the development of science and technology, the differntial inclusion is becoming a hot topic in the uncertain control theory. This project considers Lure's differential inclusion control systems whose linear parts may hold some parameters while the set-valued functions satisfy maximal monotonous property. The project studies the design problems of input-state stabilization and observer for this class control systems. For the stabilization, it applies Lyapunov theorem and control Lyapunov function to establish stabilizing conditions. Furthemore, the result will be extended to the stabilization of parameter systems. We propose the reduced order observer design approach by estimating the set-valued functions output from output equation and establish the novel observer design theory of differential inclusion systems using adaptive observer design technique.
