中文摘要: 本项目针对具有分段不确定转移率的随机Markov跳变-切换时延系统,深入研究系统在三种补偿方式(立即补偿﹑时延补偿﹑预先补偿)下的有限时间静态和动态抗饱和补偿设计问题。在此基础上,分别针对带有有界外部干扰和随机外部干扰(维纳过程)的随机Markov跳变-切换时延系统,采用L2/l2增益分析法﹑采样控制技术和广义伊藤公式等工具,研究它们在分段不确定转移率下的干扰抑制问题。对结果进行仿真实验,检验设计方法的有效性。本项目研究旨在探索建立一套随机Markov跳变-切换系统有限时间抗饱和补偿控制理论,分析饱和非线性对此类系统控制综合的影响,进而提出行之有效的抗饱和补偿控制策略。本项目从跳变转移率﹑时延和饱和入手,运用多种研究方法,是研究跳变系统的前沿性课题。

英文摘要: For stochastic Markov jumping-switching delayed systems with piecewise-uncertain transition rates/probabilities, this program will study the problems of static/dynamic anti-windup design with three compensation activations (immediate activation, delayed activation, anticipation activation) in depth. Based on these, the disturbance attenuation control problem will be addressed for stochastic Markov jumping-switching delayed systems with the bounded external disturbance and random external disturbance (Wiener process), respectively, by using the tools, such as the L2/l2 gain analysis,sampled-data control and generalized Ito formula. It will give some simulations to show the effectiveness of the proposed methods. The purpose of this project is to explore and establish finite-time compensation control theory of Markov jumping-switching delayed systems, analyze the influence of saturation nonlinearity on the control synthesis of the systems and put forward some effective anti-windup compensation control strategies. This project will begin to analyze transition rates/probabilities, time delays and saturation and various research methods will be used. It is a frontier subject in the field of the study of jumping systems.
