中文摘要： 本项目研究具有输入饱和因子的广义时滞系统的分析与控制问题。首先研究在输入饱和因子和反馈影响下，受控系统的性能改变。特别是，细致地刻画系统动态阶的改变和脉冲行为，以及对初始状态的敏感性，分岔、失稳和混沌现象。进而探讨具有输入饱和因子和时滞的广义系统结构性质的鲁棒性和稳定性，以及相关的控制问题。借助于矩阵不等式方法，以及Matlab软件，求解出对应的控制器，并给出控制器的设计方法和仿真程序。这些控制包括鲁棒控制、分散控制、混沌控制和带有性能指标的优化控制。由于脉冲行为、时滞及饱和因子的存在，该研究复杂且具有相当的难度。本项目将拓宽广义系统的研究领域，同时提供广义系统分析与控制的新方法和新理论。从而无论对广义系统控制理论本身的发展还是对实际控制工程的应用都具有非常重要的理论意义和学术价值。

英文摘要： The problems of the analysis and control for singular time-delay systems with input saturating actuator are investigated in this project. The performance change of the controlled system is firstly studied under the influence of the saturating actuator and feedback. In particular, the dynamic order change and impulse behavior of the system are depicted meticulously as well as the sensitivity of the initial state, bifurcation, instability and chaotic phenomenon. Robustness, stability and relevant control problems are discussed further for singular time-delay systems with input saturating actuator. By means of matrix inequality method and the Matlab software, the corresponding controllers are solved ,and the controller design methods and simulation programs are given. These controls include robust control, decentralized control, chaotic control and optimization control with performance index. As for the existence of the impulse behavior, time-delay and saturating actuator, the study is complex and rather difficult. This project will broaden the study field of the singular systems and provide the new method and new theory of the analysis and control for singular systems. This project has very important theoretical significance and academic value to the singular systems control theory development as well as the actua
