Abstract :
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.
