Abstract

With the capability of high speed flying, a more reliable and cost efficient way to access space isprovided by hypersonic flight vehicles. Controller design, as key technology to make hypersonic flight feasibleand efficient, has numerous challenges stemming from large flight envelope with extreme range of operationconditions, strong interactions between elastic airframe, the propulsion system and the structural dynamics.This paper briefly presents several commonly studied hypersonic flight dynamics such as winged-cone model,truth model, curve-fitted model, control oriented model and re-entry motion. In view of different schemes such aslinearizing at the trim state, input-output linearization, characteristic modeling, and back-stepping, the recentresearch on hypersonic flight control is reviewed and the comparison is presented. To show the challenges forhypersonic flight control, some specific characteristics of hypersonic flight are discussed and the potential futureresearch is addressed with dealing with actuator dynamics, aerodynamic/reaction-jet control, flexible effects,non-minimum phase problem and dynamics interaction.
