Abstract:	Hypersonic aircrafts fixing with ramjet mostly adopt wave rider configuration. Due to the large flight envelope and obvious aerodynamic changes, variable geometry inlet design is adopted to improve the comprehensive propulsion performance under different flight conditions, which makes the variation of dynamic characteristics more complicated, and the coupling effect between flight and propulsion more obvious. Under this background, the dynamic modeling of the hypersonic vehicle with variable inlet is studied. The flight mechanics and dynamics characteristics of aircraft in a wide speed range are analyzed under different inlet configurations. On this basis, an adaptive integrated control method based on the dynamic parameter dependencies is proposed to realize the flight/propulsion coupling feedback control strategy. Meanwhile, by adjusting the controller in real time, the command tracking quality is improved when the aerodynamic parameters are changed due to the flight environment and the variation of the inlet.
