中文摘要： 高超声速飞行器控制研究具有重要的科学和军事意义，是我国目前重点鼓励和支持的研究领域之一。特别是高超声速飞行器HTV-2在两次发射中出现了同样的失稳问题，由于气动加热对于高超声速飞行器的稳定性具有重要影响，因此研究其热气动弹性问题具有重要的现实意义。基于特征模型的自适应控制在理论和应用中取得了重要进展，在交会对接中的成功应用表明该方法具有重要的实际应用前景。本课题将延续上一个已结题国家自然科学基金项目的研究，借助于申请者在特征建模理论和高超声速飞行器自适应控制研究中积累的理论研究成果，以高超声速飞行器热气动弹性控制问题为背景，研究高超声速飞行器热气动弹性建模、高阶时变非线性系统的特征建模、基于特征模型的自适应控制及其稳定性等基础理论问题，建立一套高超声速飞行器实用的建模与智能自主控制的典型理论和方法，为高超声速飞行器控制奠定理论基础，并进一步推动特征模型理论的发展。

英文摘要： The research on hypersonic flight vehicle control has great significance in both science and military aspects and is one of the encouraged and supported important research fields in China. The same unstable problem of the hypersonic vehicle HTV-2 happened in its two lauches shows the difficulty of this research. It has great practical meaning to study the thermoaeroelasticity problem, because of the influence of aerodynamic heating on the stability of hypersonic vehicle. The theory and application of characteristic model based adaptive control make great progresses. Especially, the successful application in rendezvous and docking shows that the method has important prospects in practical applications. This project follows the previously finished project of National Natural Science Foundation, based on the theoretical research achivements of the applicant on characteritic modeling theory and adaptive control research on hypersonic vehicle. With the background of control problem of hypersonic thermoaeroelasticity, it will be studied that thermoaeroelasticity modeling of hypersonic vehicle, characteristic modeling of high-order time-varying nonlinear system, characteristic model based adaptive control, and its stability and as such basic theory problems to establish the typical theory and methods for hypersonic ve
