组合动力空天飞行器控制问题研究

The aerospace vehicle is a new generation of round-trip transportation system flying through dense atmosphere, near space and near-earth orbit. The use of combined power will bring control problems caused by multi-mode operation and switching, especially under the complex multiple constraints of the ascent flight, which will bring great challenges to the stable flight. Aiming at the control problems of the ascent flight of the aerospace vehicle, the impacts of combined power multi-mode operation and switching on the aerospace vehicle are discussed from four aspects: dynamic characteristics, trajectory optimization, guidance technology and attitude control technology. The main problems faced are analyzed in detail, the difficulties and research status of various key technologies are sorted out, and the future development direction is foreseen.
