摘要：
The problem for rapid lunar exact-landing trajectory optimization is studied using Gauss Pseudospectral Method (GPM) in this paper. In process of solving the optimal control problem, control variables and state variables are dispersed, and control variables and flying time are used as optimal variables. Aiming at the characters of GPM, a solving strategy from initial value to high accurate parameters is designed. By using this method, the attainable region for lunar landing is obtained, and an optimal trajectory for exact-landing is designed. Simulation results show the methodology and strategy for the optimal trajectory designing have good robustness and strong convergence.
