摘要
重点研究了在固定时间内利用主矢量原理判断近距离冲量拦截轨道燃料消耗是否最优的问题,并对非最优情况提出了优化策略.根据轨道动力学理论,建立了近距离空间拦截轨道的数学模型.根据主矢量理论给出了判断冲量拦截是否最优的理论依据,并给出了优化方法.利用仿真算例证实了优化的有效性.通过对不同时间的空间拦截燃料消耗进行仿真比较分析,提出了燃料消耗最优的拦截策略.
In this paper,the optimum of the fuel consumption in close impulse interception within a fixed period of time by principal vector theory was mainly studied.Then a mathematical model of space interception of short distance based on the theory of orbital dynamics was set up.According to the principal vector theory,a theoretic criterion was put forward to determine whether the optimum of impulse interception has been attained,and an optimization technique for the interception was raised too.The effectiveness of the optimization was verified by lots of simulation examples.In the latter part of the paper,the fuel consumptions of the space interceptions at different time were simulated,compared and analyzed,and at last a technique to achieve optimal fuel consumption of the interception was brought forward.
