OpenMDAOを利用して軌道最適化問題を解いてみました。連続時間の最適制御問題を最適化問題に変換してSQPで解いています。
技術的背景、実装などについては下記を参考にさせていただきました。

Solving Optimal Contorol Problem with OpenMDAO.
Converting continuous time optimal control problem into optimization problem,
solved using SQP method.
This example is trajectory optimization of flying object being dominated its
motion by Gravity and with some initial conditions.
Really simple EoM is implemented to evaluate usage of OpenMDAO on this type of problem.
default condition is as follows:
-Evaluation Function is arranged to minimizing time.
-State variables are velocity, position and path angle(NOT AOA).
-Can handle both equal and in-equal restraint condition.
These conditions are really easy to rearrange.
