Review of Guidance and Control Approaches for Air-Breathing Hypersonic Vehicle

The flight speed and height of hypersonic vehicle change dramatically, which results in very complicated aerodynamic characteristics, highly nonlinear and strongly coupled dynamic model.Moreover, there are several strict constraints on flight trajectory, such as thermal speed, atmosphere stress, over loading and so on.Therefore, the guidance and control problem of hypersonic vehicle is extremely challenging.The characteristics and disadvantages of each method were thoroughly analyzed.Furthermore, the focuses in guidance and control field were proposed for future research.
