摘　　要：针对失效航天器大型天线进行再利用过程中的多细胞卫星(Satlet)布局问题,推导基于Lagrange方程的多Satlet天线动力学方程。通过分析天线振动对Satlet布局位置的影响和Satlet对天线系统的扰振,提出Satlet布局规划过程中的约束条件。在此基础上,采用遗传算法给出Satlet在天线系统中的最优布局,并采用协方差矩阵自适应进化策略(CMAES)对结果进行校验,以保证Satlet最优位置的准确性。仿真结果表明,失效航天器系统采用由上述优化算法给出的最优位置对Satlet进行布局,可以使得失效航天器的大型天线完成再利用过程中的姿态控制任务。Aiming at the problem of muhi-Satlet layout plan in the process of the reuse of the retired satellite＇ s large scale antenna, the multi-Satlet antenna dynamics equation is derived based on Lagrange equations. By analyzing the effect of the antenna vibration on location of Satlet layout and the vibration effect of Satleton antenna system,the antenna system＇ s Satlet layout planning constraints are proposed. And then, the genetic algorithm is used to optimize Satlet layout positionin multi-antenna system, and the optimal location of Satlet in antenna system is given. Then the eovariance matrix adaptation evolutionary strategy （CMAES） is used to validate the accuracy of optimal Satlet position given by the genetic algorithm. The numerical simulation is proposed at last and is used to demonstrate that the retired spacecraft antenna＇ s attitude control project is valid in the reuse process when the optimal Satlet position is accepted in the retired spacecraft system.
