摘要
针对临近空间低动态飞行器出现的新的控制问题,分析和总结了临近空间低动态飞行器控制进展状况和发展趋势。首先,基于飞艇和浮空器等临近空间低动态飞行器的特点,归纳总结了其飞行控制问题。在此基础上,结合这类飞行器的当前发展状况,从飞行器控制角度出发,着重介绍总结了临近空间低动态飞行器在控制系统执行机构配置、数学模型、姿态控制、定点控制、速度控制、航迹优化、轨迹跟踪控制、升空和返回控制、压力控制,以及应用的多种控制策略的研究进展。最后,在已有的控制问题研究发展的基础上,提出了临近空间低动态飞行器在控制研究领域所要解决和关注的若干问题。
The latest development and tendency of the flight control systems for low dynamic vehicles in the near space is analyzed and summarized in view of the new problems in the research of the control technology.Firstly,based on the characteristics of the vehicles,including near-space airships and stratospheric balloons in different flight environments of stratosphere and troposphere,the basic problems and key technologies of the low dynamic vehicles are generalized.Secondly,special attention is paid to the following areas in flight control system design for low dynamic vehicles：the servo control system design,mathematical models,attitude control,station-keeping control,velocity control,trajectory optimization,path tracking control,ascent control,descent control,pressure control,and control strategies in applying all kinds of control approaches.Finally,some key issues are proposed which deserve more attention of the researchers for their solution on the basis of the progress of existing research in relevant fields.
