摘要:
航天器追逃博弈是空间竞争非常重要的一个方面,是当前航天领域的一个研究热点。文章基于生存型微分对策理论对航天器追逃博弈进行了研究,首先采用优化算法实现对追逃两航天器的博弈过程的初步求解,而后利用牛顿迭代法对该问题进行精确求解,并通过遗传算法、差分进化算法以及蚁群算法3种优化算法的性能对比,得出蚁群算法是一种较为有效的求解追逃博弈问题初值的优化算法。仿真结果表明,追逃博弈主要发生在Oxy平面上,并且追踪航天器推力加速度越大,其在博弈过程中的优势地位会越趋明显;同时两航天器之间的推力加速度相差越大,追逃博弈的时间会越短,但这种效果会随推力加速度差值的增大而逐渐减弱。
Abstract:
Spacecraft chasing game is a very important aspect of space competition and a research hotspot in the current aerospace field. Based on the survival differential strategy theory, it studied the spacecraft pursuit game. Firstly, an optimization algorithm is used to realize the preliminary solution to the spacecraft pursuit process, and then the Newton iteration method is used to solve the problem accurately. By comparing the performances of the three optimization algorithms, the ant colony algorithm is a more effective algorithm for solving the initial value of the chasing game problem. Simulation results show that the pursuit game mainly occurs on the Oxy plane, and the purser’s dominant position in the game will become more and more obvious due to its large thrust acceleration. At the same time, the greater the difference in thrust acceleration between the two spacecrafts, the shorter the time to the pursuit game, but this effect will gradually decrease as the thrust acceleration difference increases.
