Control of Hypersonic Vehicle Based on Improved QFT

Hypersonic vehicle has high military value in terms of real-time reconnaissance, remote rapid deployment and precision strike, especially the implementation of real-time reconnaissance mission has unique advantages. Efficient thrust, the aircraft must be flying high dynamic pressure conditions, in order to control the resulting aerodynamic heating and aerodynamic drag for the hypersonic vehicle angle of attack for precise control, at the same time, the dynamic characteristics of the hypersonic vehicle conventional aircraft are very different, the most critical aerodynamic characteristics are good enough stability of the pre-degree in terms of the control system must have a very strong robust feedback system. the QFT method, using an improved design of hypersonic flight longitudinal channel controller. Simulation results show that the robust controller design meets the system requirements.
