N2 - To reduce the influence of the aerodynamic nonlinearity on the control system design for hypersonic vehicles, improving aerodynamic nonlinearity is proposed as an optimum target for the overall design. With the definition of DONL (degree of the nonlinearity), Newton Impact Theory and Shock-Expansion Wave Theory are applied to model the aero dynamic nonlinearity expressed in terms of with configuration parameters. A Genetic Algorithm is used to search for the optimal configuration parameters for the lowest DONL. Finally, considering the basic configurational characteristics of hypersonic vehicles', the control-configured optimum method is selected. This method is verified to be correct and effective through analyzing an sample vehicle's optimization.
