英文摘要: Aimed at meeting the urgent demand for hypersonic vehicles dynamic model when analyzing dynamic characteristics and designing flight control system for near-space hypersonic vehicles, this project researches mainly on hypersonic vehicles aerodynamics in the environment that gas flow is high-altitude, high-speed and unsteady. After research achievements of aerodynamics and control theory are integrated, dynamic modeling method that really describes dynamic characteristics of near-space hypersonic vehicles and new model validation method of dynamic model in poor experimental conditions are explored. Control-oriented vehicle dynamic model is built and model confidence is assessed to lay the foundation for vehicles dynamic characteristics analysis and flight control system design. The mentioned achievements provide theoretical guidance and technical support for theory research and engineering design of near-space hypersonic vehicles flight control systems in our country. In addition, the control theory research in our country is developed and control theory and engineering subject is promoted. Integration project groups approach is employed and experts in the fields of control theory and aerodynamics are gathered. This project integrates research achievements of major projects about control and aerodynamics and
