电推进器动力系统卫星轨道优化控制仿真

摘要

Based on the feasibility of using the electric thruster in the micro/nano satellite,the perform-ance of the micro/nano satellite orbit control is simulated.By using the resistance heating type electric thruster with better overall performance as the power plant of the micro/nano satellite, a layout scheme of the resistance heating type electric thruster on the micro/nano satellite is given,and the micro-nano sat-ellite with charged thruster.The orbit model and the thrust calculation verify that the layout can realize satellite six-degree-of-freedom control.Finally,according to different satellite orbit requirements,the a-mount of propulsion needed to achieve satellite orbit control is analyzed,which will provide some refer-ences for improving the capability of micro /nano satellite in space mission and expanding the application space of micro and nano satellites.%基于电推进器运用于微纳卫星的可行性探讨,仿真分析了微纳卫星轨道控制性能.通过将综合性能更优的电阻加热型电推进器作为微纳卫星的动力装置,给出一种电阻加热型电推进器在微纳卫星上的整体布局方案,建立了带电推进器微纳卫星的轨道模型,推力计算验证了布局可实现卫星的六自由度控制.最后,针对不同的卫星变轨需求,分析了实现卫星变轨控制所需的推进剂量,从而为提升微纳卫星完成空间任务能力,拓展微纳卫星的应用空间提供一定的参考.
