摘要
为了使固体微推力器阵列更具实用性,提出了一种适用于一体化控制的推力器布局方法;对基于固体微推力器阵列的推力器姿轨控分配算法问题分别进行了建模,引入了成本概念,保证推力器使用个数最少;将动态规划及贪心策略思想引入到了推力器分配问题求解中,建立了求解数学模型,进行了算法实现;对用于一体化控制中的推力器分配问题以及信息共享问题进行了分析。经过算法分析及仿真验证,该方法能有效快速求解该问题,有利于实现实时控制,能满足一体化控制的要求。
In order to make solid propellant micro-thruster array more practical, the layout method which can be used in attitude and orbit control was proposed. The mathematical model of allocation algorithm was established and the concept was introduced to ensure that the least thrusters were used. The dynamic programming and the greedy strategy were introduced into the problem and the solving mathematical model was established. Through analysis and simulation, this method can effectively solve the problem, which is conductive to achieve real-time control.
