Mars Entry Trajectory Quick Optimization Method for Lifting Vehicle Based on Adaptive GPM

  • 摘要: 针对升力式火星飞行器定点着陆任务的轨迹优化问题,给出了基于自适应伪谱法的快速优化算法.综合考虑探测器火星大气进入过程中的动力学约束、边界约束、路径约束以及控制约束条件,利用自适应伪谱法将轨迹优化问题转换为离散的非线性规划问题,采用序列二次规划算法进行求解,得到性能指标最优的进入轨迹.通过仿真验证,给出了实现火星进入过程燃料消耗最优的状态量和控制量轨迹.仿真结果表明,在Matlab中采用自适应伪谱法,能够在800s内采用267个配点,给出近似精度为10-6的火星进入过程中消耗能量最优的参考轨迹.
