Research on Posturalłdamage-mitigating control of Air-breathing Hypersonic Vehicles Based on Improved Prescribed Performance

In order to enhance the penetration capability of the Hypersonic Flight Vehicle, this paper analyzes the key variables that affect the maneuverability of the Hypersonic Flight Vehicle and seeks effective strategies to enhance its maneuverability. Firstly, this paper establishes the force model of the Hypersonic Flight Vehicle; secondly, establishes the maneuvering force model of the Hypersonic Flight Vehicle; finally, the key variables that affect the maneuverability of the Hypersonic Flight Vehicle are analyzed through simulation. The simulation results show that the angle of attack and height are key variables that affect the normal maneuver of the flight vehicle, and the angle of attack and the rudder deflection angle are key variables that affect the tangential maneuver of the flight vehicle. If control the angle of attackthe rudder deflection angle and height, the maneuverability of the flight vehicle will be effectively improved and the penetration capability of the flight vehicle will be enhanced.
