Hypersonic vehicles often use the aerodynamic configuration and light materials such as lifting body and waverider, which leads to the unmatched uncertain control problems caused by strong coupling characteristics and interference during reentry. To solve these problems, firstly, this paper analyzes the key factors and uncertainties that affect the attitude motion of hypersonic vehicle. Secondly, it studies the modeling and verification of rigid body and elastic body of hypersonic vehicle, establishes the error model with disturbance observation compensation, and proposes a new attitude control scheme of hypersonic vehicle, which realizes the stable tracking of attitude angle and improves the uncertainty of key parameters of the system. The simulation results show that the performance index meets the requirements and has good robust performance in the presence of unknown disturbance.

高超音速飞行器通常使用空气动力配置和轻质材料（例如举升体和行波器），这会导致无与伦比的不确定控制问题，这些问题是由强大的耦合特性和再入期间的干扰引起的。为了解决这些问题，本文首先分析了影响高超声速飞行器姿态运动的关键因素和不确定性。其次，研究了高超声速飞行器刚体和弹性体的建模与验证，建立了具有扰动观测补偿的误差模型，提出了一种新的高超声速飞行器姿态控制方案，实现了姿态角的稳定跟踪，提高了不确定性。系统的关键参数。
