提出了圆轨道辐射开环绳系卫星编队的展开控制策略。首先采用拉格朗日方程建立了辐射开环绳系卫星编队的展开动力学模型,分析了主星姿态与绳长在展开过程的动力学耦合关系;随后以建立的动力学模型为基础,分别研究了编队在重力梯度力补偿和无补偿两种情况下的自旋展开控制策略,通过规划绳系释放速度、主星自旋角速度等变量,实现了绳系编队的有效展开;最后搭建了编队自旋展开的动力学模型,通过数值仿真对所提出的展开策略进行验证,仿真结果表明:在重力梯度力矩补偿和无补偿的情况下,所提出的展开控制策略能够保证编队稳定展开。
Proposed a circular orbit radiation open-loop rope formation deployment control strategy. Firstly, the dynamic model of satellite formation with radiated open-loop rope system is established by using Lagrange equation. The dynamic coupling relationship between the attitude of main star and the rope length in the unfolding process is analyzed. Then, based on the established dynamic model, The strategy of spin-spread control of formation in both gravitational-gradient force compensation and non-compensation cases is proposed. The effective deployment of the rope formation is achieved by planning the release speed of the tether and the spin speed of the main star. Finally, the formation spin The simulation results show that under the condition of gravity gradient moment compensation and no compensation, the proposed deployment control strategy can ensure the stability of the formation.
