Reinforcement Learning for Low-Thrust Trajectory Design of Interplanetary Missions

1 code implementation19 Aug 2020 Alessandro Zavoli, Lorenzo Federici

This paper investigates the use of Reinforcement Learning for the robust design of low-thrust interplanetary trajectories in presence of severe disturbances, modeled alternatively as Gaussian additive process noise, observation noise, control actuation errors on thrust magnitude and direction, and possibly multiple missed thrust events.
