Research on Attitude Damage-Mitigating control of Air-breathing Hypersonic Flight Vehicles Based on Prescribed Performance

Abstract

In order to delay the damage accumulation of the Air-breathing Hypersonic Flight Vehicle when it performs tasks efficiently, this paper designs a prescribed performance attitude damage-mitigating controller to achieve the above purpose. Firstly, established the flight vehicle’s force model and the damage dynamics model. Secondly, the concept of induced angle of attack is introduced, and a longitudinal short-period attitude model of the flight vehicle is established considering elasticity. Then, a prescribed performance attitude damage-mitigating controller is designed. The simulation results show that, on the basis of considering elastic factors, the attitude damage-mitigating controller can effectively delay the damage accumulation during the flight of the Air-breathing Hypersonic Flight Vehicle, while ensuring the mission performance, which provides an important reference in the future for maintaining the balance between mission performance and damage accumulation of flight vehicle.
