摘要
在考虑第一次脉冲位置变化情况下 ,推导了航天器双冲量交会时的优化模型 ,以此为基础构造了最优交会的燃料 -时间混合优化指标 ,并设计了与之相应的遗传算法。仿真结果表明 ,考虑和不考虑第一次脉冲位置 ,优化指标值相差悬殊 。
Considering the influence of the first impulse's position, the model of rendezvo us between two spacecrafts using two impulses is derived. Based on that, optimal rendezvous object considering of fuel and time is constructed, and GA (Genetic Algorithms) is designed. Simulation results show that the value of performance index, considering the influence of the first impulse's position, is better than that if not considering, and prove the design fo GA is successful.
