摘要
针对载人飞船月地返回飞行任务,提出一种基于双重优化算法的两层串行求解策略。轨道初步设计阶段,在改进的双二体模型下采用差分进化算法与序列二次规划算法相互补的双重优化算法进行轨道初值的求解。高精度修正阶段,在高精度模型下利用序列二次规划算法修正了初步设计的结果。仿真算例的结果验证了该策略的有效性和可行性,并显示出求解精度高、收敛性好的特点。最后,利用该方法进行了大量的仿真计算,对月地返回轨道可达域、速度增量等轨道特性展开了分析。
The two-level serial solution strategy is established for the Moon-Earth return mission of manned spacecraft based on hybrid optimization algorithm. First, the initial trajectory is obtained by adopting hybrid optimization algorithm consisting of differential evolution method and sequence quadratic method under the improved double two-body model. Then the sequence quadratic method is applied to obtain the final trajectory under the high precise dynamic model. The effectiveness and reliability of the approach proposed are demonstrated by the simulation tests, and the high precision and excellent convergence of the proposed method are indicated. Finally, according to a great deal of simulation results by the method, the trajectory characteristics such as the reachable set and velocity change are analyzed.
