OPTIMAL CONTROL OF ORBIT TRANSFER OF SPACE PROBE WITH FINITE THRUST

摘要

The minimum-fuel orbit transfer with finite thrust is studied here. The optimization of the dynamic equations including the control parameters shows that the optimal values are constants. The initial true anomaly f_0, yaw angle ψ and the dive angle φ are selected as the start values of the iteration method. And the constraint conditions in the Two-point Boundary Value Problems are presented. Finally, two numerical examples of optimal orbit transfer are calculated and discussed. The results showing the optimal method in the paper is feasible.
