Curriculum-Driven Deep Reinforcement Learning for Autonomous Far-Range Rocket Landing

Read the original on arXiv AI →

The paper introduces a curriculum-driven deep reinforcement learning framework for autonomous far-range rocket landing. It uses a three-stage curriculum, critic warm‑up, rehearsal to avoid catastrophic forgetting, and a high‑dimensional observation vector with a full 3×3 rotation matrix. The redesigned reward function bounds per‑step rewards and accumulates progress, yielding a 99.98% success rate over 100,000 episodes, far surpassing the baseline.

Curriculum-Based Deep Reinforcement Learning for Robust Autonomous Rocket Landing under Atmospheric Uncertainty

The paper introduces a curriculum-driven proximal policy optimization framework for three‑dimensional autonomous rocket landing in stochastic atmospheric conditions. Learning is structured into far‑range approach, soft descent, and integrated landing stages, with techniques such as policy transfer, critic warm‑up, rehearsal, and progressive weather severity. In 100,000 evaluation episodes the policy achieved a 96.656% success rate, with performance decreasing to 88.07% under the highest weather‑severity band and small miss distances and low residual velocities at touchdown.

Adversarial Reinforcement Learning for Robust Planetary Landing

The paper presents a method for improving the robustness of deep reinforcement learning (DRL) policies used in planetary landing by employing adversarial reinforcement learning. A secondary agent generates physically constrained perturbations that challenge the landing controller, creating an asymmetric zero‑sum game. Training is conducted in three stages—baseline learning, stochastic robustness enhancement, and iterative adversarial optimization—showing that adversarial disturbances uncover vulnerabilities missed by conventional randomization and hint at better generalization to unseen perturbations.
