Design of Control for Hypersonic Vehicle Based on Fuzzy Adaptive

Because of airframe-propulsion integrated configuration design,the air-breathing hypersonic scramjet vehicle's accurate aerodynamic characters are difficult to obtain.According to this character,a control method combining adaptive and fuzzy control is presented.Even if vehicle's aerodynamic characters are not accurate,high control accuracy can be still obtained.Using a fuzzy adaptive control,a longitudinal control system is designed for hypersonic vehicle.The simulation results show that the controller can track the velocity and altitude command accurately with the effect of the uncertainty of the aerodynamic characters.
