ResumoThis paper uses robust pole assignment method to design an adaptive velocity and altitude tracking control algorithm for the longitudinal model of a wave rider configuration air-breathing hypersonic vehicle, which has strong coupling between structure, propulsion and aerodynamics. Base on the elastic hypersonic vehicle model CSUAL_GHV, the simulations using adaptive robust pole assignment control method and adaptive non-robust pole assignment control method are carried out respectively. The results show that, compared with the non-robust pole assignment control method, control system using adaptive robust pole assignment control method not only achieves the velocity and altitude tracking goal with tracking error less than 1%, but also the vibration motion of the hypersonic vehicle is suppressed sufficiently. Air-breathing hypersonic vehicle is a kind of aircraft flying in the near space atmosphere, which is powered by scramjet and flying faster than 5 Mach. Because of its high speed, the hypersonic vehicle can be used as a military rapid combat platform as well as a fast civilian global transportation, and thus have received much attention. The last successful flight test of the U.S. X-51A Waverider hypersonic vehicle indicates that the hypersonic flight technology has been developed gradually from the experimental stage to the practical stage. Due to the use of airframe/engine integration design technology, the hypersonic vehicle exhibits strong coupling between structural, propulsion and aerodynamics. The hypersonic
