摘要
针对期望控制力到各航天器各轴线圈电流的磁矩分配问题,提出了一种基于电磁力的集群航天器磁矩最优分配方法,将磁矩分配问题转化为一个有约束的非线性优化问题,采用模拟退火算法实现两航天器各轴线圈中电流的最优分配,使包括地磁场干扰力矩和航天器之间干扰力矩的总干扰力矩最小。仿真分析验证了该方法能够通过电流的最优分配,实现磁矩最优分配,进而实现电磁力最优分配,耗能均衡,且能够更加快速得到电流的最优分配。
In order to obtain the solution of currents of each spacecraft when the desired interdipole forces are given,an optimal dipole solution for electromagnetically controlled spacecraft cluster is proposed. Firstly,the magnetic moment allocation problem is transformed to a nonlinear constrained optimization problem,and then an optimal dipole solution is found by using simulated annealing for the total disturbance torque minimization which is caused by the earth magnetic field and the interaction among spacecraft. The simulation results show that the optimal dipole solution is valid and optimal dipole solution can be achieved according to the optimal solution of currents for the energy consumption equilibrium.
