摘要

为实现高超声速飞行器的精确控制，分析了柔性振动对高超声速飞行器飞行控制系统的影响，建立了含结构、气动、推力系统耦合和弹性冲击的非线性物理动力学模型。对弹性模态与刚性模态之间的一种主要扰动耦合进行了建模和分析。设计并仿真了扰动观测器。仿真结果验证了该方法的有效性。

Elastic disturbance modeling and analysis for hypersonic vehicle

To achieve precise control of hypersonic vehicle, the paper analyzed the effects of flexible vibration on the hypersonic vehicle flight control system, a non-linear physics-based dynamic model including the impacts of structure, aerodynamic, thrust system coupling and elastic impact for an air-breathing hypersonic vehicle was developed. One of the main disturbance-coupling between elastic mode and rigid state was modeled and analyzed. A disturbance observer was designed and simulated. Simulations results are provided to validate the proposed approach.
