中文摘要： 高超声速飞行器由于采用了超燃冲压发动机、机体/发动机一体化等先进技术以及自身复杂的气动特性，使其动力学建模与姿态控制系统设计问题成为发展高超声速技术亟待解决的重大难题之一。与传统飞行器相比，高超声速飞行器具有快时变、强耦合、强非线性以及严重不确定性等特点。针对高超声速飞行器的精确建模、飞行控制中的高稳定性与强鲁棒性等关键问题，本项目拟开展高超声速飞行器姿态控制系统的面向控制建模方法和LPV控制理论研究。项目拟按照先动力学建模后动态特性分析、先面向控制建模后控制系统设计、先刚性模态后弹性模态、先状态反馈控制设计后输出反馈控制设计、先巡航状态飞行后大包线机动飞行的思路由浅入深、层层递进，深入研究高超声速飞行器的高精度面向控制建模、基于鲁棒参数化方法的LPV控制、大包线机动飞行条件下弹性模型的LPV连续变增益控制等内容。课题研究成果不仅具有重要理论意义，而且为我国发展高超声速飞行器提供技术支持。

英文摘要： The research on hypersonic vehicles has received worldwide attention in recent years mainly due to their extensive application prospects and important strategic values. The technology of hypersonic flight is one of the most important technologies in the current and future development of aerospace fields. The development of hypersonic technology is faced with a large number of difficult problems to be solved because of the using of airframe-integrated scramjet engine and the complexity of aerodynamic characteristics. Among these problems, seeking better control-oriented model and designing effective attitude controller for the flight control systems of hypersonic vehicles are one of the major tasks in developing hypersonic vehicle technology. Compared with traditional flight vehicles, the design of flight control systems for hypersonic vehicles is a highly challenging task due to the unique characteristics of the vehicle dynamics, such as fast time-varying parameters, variously strong coupling effects, high nonlinearities, and grave uncertainties. Aiming at the key issues to accurate modeling, rigid stability, strong robustness and other control performances of hypersonic flight control systems, we will propose the control-oriented modeling methods and linear parameter-varying (LPV) control strategies for the att
