摘要
结合多约束再入飞行任务,以升力式再入飞行器为研究对象,给出完整的弹道优化模型,研究弹道优化数值解法,并采用高斯伪谱法进行求解计算,得到满足相应约束条件的再入飞行轨迹。仿真结果表明,高斯伪谱法能够求解此类多约束飞行轨迹优化设计问题,并具有较好的效果。
Trajectory optimization for a lifting reentry vehicle is researched in the paper. Firstly, a complete model for this problem is proposed and the numerical solution theory for trajectory optimization is studied. Then, the Gauss pseudospectral method （GPM） is used to solve the trajectory optimization problem, and finally the optimization trajectory which satisfies corresponding constraints is obtained. The simulation results show that GPM can solve multi-constraints trajectory optimization problem with good results.
