【摘要】：研究太阳帆的力学特性和轨道控制设计方法,导出太阳帆的无奇点控制律.提出通过STK中MATLAB语言编写的嵌入式脚本(Plug-in Script)来将由控制律得到的光压力加速度矢量,添加到STK轨道计算力学模型中,从而进行轨道控制的方法.仿真结果表明,对于常规方法难以进行仿真分析的航天器动力学模型(如太阳帆),所提出的方法能快速灵活地支持其相应的任务,并增强任务场景的可视化,从而实现利用STK丰富的功能特性进行复杂航天任务的设计、分析和验证.
[Abstract]:The mechanical characteristics of solar sail and the design method of orbit control are studied, and the control law of solar sail without singularity is derived. An embedded script (Plug-in script) written by MATLAB language in STK is proposed to add the photo-pressure acceleration vector obtained from the control law to the computational mechanics model of STK orbit, so as to carry out orbit control. The simulation results show that the proposed method can quickly and flexibly support the corresponding tasks and enhance the visualization of mission scenarios for spacecraft dynamics models (such as solar sail), which are difficult to be simulated by conventional methods. Thus, the design, analysis and verification of complex spaceflight missions can be carried out by using the rich functional characteristics of STK.
