摘要

将一种源自二阶锥规划的凸化方法应用于具有凹避碰约束的多卫星编队重构问题。引入几何相对轨道元,直观地描述地层形态。该算法由外部凸化迭代组成,并提出了高斯伪谱法来处理非凸转移轨迹规划问题。数值算例验证了该方法的有效性,并分别与凹不等式约束的球面近似和矩形近似进行了对比仿真,结果表明该算法在能量优化方面有明显改善。

Multiple spacecraft formation reconfiguration planning with nonconvex collision avoidance constraints
A convexification method originating from second order cone programming is applied to multiple satellites formation reconfiguration problems with concave collision avoidance constraints. Geometric relative orbit elements are introduced to straightforward depict formation configurations. Algorithm consists of external convexification iterations and the Gauss pseudospectral method is presented for coping with nonconvex transfer trajectories planning. Numerical examples are implemented for validating the proposed approach, and contrast simulations separately with spherical and rectangular approximations of concave inequality constraints are carried out, results indicate a manifestly improvement in energy optimization with the algorithm presented here.
