Control-oriented Modeling for Hypersonic Vehicle Control

Hypersonic vehicles have great promising in civil and military application. The physics related to hypersonic flight is quite different from traditional aircraft, such as strong nonlinear, strong aerodynamic coupling and so on. In this work, we apply oblique-shock theory and Prandtl-Meyer flow to obtain a control-oriented model for a hypersonic flight. The results compare well with results of computational fluid dynamics, but can be achieved much quicker. which is preferred for control investigation. As an example, a complete feedback control system for the flight model is demonstrated in the end of this paper.
