中文摘要： 导引与控制系统是导弹实现精确打击的关键系统。与传统的设计方法相比，导引与控制一体化设计在减小导弹需用过载、降低脱靶量、提高系统的可靠性与稳定性等方面更具优势。现有的考虑多通道耦合的导引与控制一体化方法存在不能保证系统的鲁棒性和没有考虑舵偏角幅值限制的不足。本项目将为克服这些不足而展开研究工作。首先，将所建立的导引与控制一体化全耦合设计模型抽象成为一类典型的MIMO不确定非线性系统，并研究其鲁棒自适应抗饱和控制方法。然后，利用所得的理论结果解决具有输入饱和非线性的导引与控制一体化全耦合设计问题，并进一步解决同时具有末角约束和输入饱和非线性的导引与控制一体化全耦合设计问题。本项目的宗旨是针对一类典型的MIMO不确定非线性系统，提出简单易行且具有良好性能的鲁棒自适应控制方法，并提出一套完整且实用性强的导引与控制一体化全耦合设计方法，为导引与控制一体化设计技术的工程实用化提供理论支持。

英文摘要： The missile guidance and control system plays a key role in precision target interception. Compared to the traditional guidance and control system design method, integrated guidance and control system design methodology has more advantages in reducing the desired overloads, reducing the miss distance and improving the reliability and stability of the whole system. It is noted that the robustness of the closed-loop system can not be ensured and the unavoidable input saturation problem is not considered in the existing integrated guidance and control design methods considering the coupling among different channels. Hence, this project is aimed to overcome these shortages. Firstly, a typical MIMO uncertain nonlinear system is abstracted from the design model for fully integrated guidance and control system, and its robust adaptive anti-windup control problem is further considered. Then, the obtained theoretical results are used to solve the fully integrated design problem of guidance and control systems considering input saturations. Based on this, the fully integrated design problem of guidance and control systems considering constraints on terminal attitude angles and input saturations is further solved. The objective of this project is to propose a complete and practically applicable intagrated guidance and cont
