摘要
针对空间攻防领域的需求,基于微小卫星编队提出一种聚光操控技术,利用编队内卫星的协同控制聚集太阳光到目标卫星上,造成局部过热甚至烧毁。首先,基于CW方程设计微小卫星聚光编队,分析表明该编队聚光效率较高但需要一种高精度姿轨控算法来支撑。然后,根据任务需求设计基于卫星本体系的姿轨耦合二阶滑模控制算法。最后,通过仿真证明该算法满足编队卫星实现聚光跟随的要求,验证了微小卫星聚光编队在空间攻防领域的可行性。
Regarding the demand of space attack-defense,a light control technique based on small satellite formation is proposed,which cause local overheating even burning by using cooperative control of satellites that concentrate sunlight onto the target satellite. First of all,based on the CW equation,the light-control small satellite formation is designed. The analysis shows that this formation has high condensing light efficiency but requires a high-precision control algorithm for satellite attitude and orbit to support. Then,based on the task demand,a second-order sliding mode control is designed for satellite attitude and orbit based on system of proprio-coordinate. Finally,the simulation is proven that the algorithm meets the requirements of the light control and verifies the feasibility of the small satellite formation in space attack-defense.
