Traditional methods for rocket orbiting have serious deficiencies in orbital accuracy and computational efficiency, and cannot handle engine failure which leads to thrust drop. Accordingly, this manuscript designs a trajectory planning algorithm based on DDPG for the launch vehicle into orbit, transforms the rocket orbiting into an MDP problem, and constructs reward functions that satisfy the flight process and terminal constraints. The simulation results show that this method has significantly improved the accuracy of orbiting and calculation efficiency, and has the ability to adjust to suitable orbit adaptively under failure.
