航天飞行器飞行模态辨识技术应用及展望

Application and prospective outlook of the aerospace vehicles' operational mode identification

介绍了航天飞行器飞行模态辨识的应用案例和研究展望。首先,阐述了飞行模态辨识的意义和国内外研究现状,给出了美国Ares I-X火箭飞行模态辨识应用的案例,据此分析了该案例对后续研究的启示;最后详细阐述了飞行模态辨识应用的展望,将后续研究分为三个阶段,从现有算法研究及鲁棒增强,到针对飞行环境的飞行模态辨识算法的开发,再到飞行器弹性智能控制的应用。

The application and prospective outlook of the aerospace vehicles’operational modeidentification is discussed.Firstly,the significance and the investigation status is put forward.Secondly,the application case of the Ares I-X in-flight modal identification is described,and the reveal to the extendresearch is derived.At last,the prospective outlook of the hypersonic aircraft’s operational modeidentification is analysis,where the study is decomposed as three phases,which include the investigationand development of existing arithmetic,operational mode identification technology based on the colorednoise,and the intelligent control of the aircraft.
