要旨で参照されている関連研究は明示されていないが、同分野の定番として、DRL を用いたクアッドコプター制御の基礎論文(例えば、Hwangbo et al. の "Learning agile and dynamic motor skills for legged robots" や、OpenAI の "Emergent tool use from multi-agent autocurricula" など)や、actuator dynamics を考慮した制御手法(例: モデル予測制御)に関する論文が考えられる。具体的には、DRL と物理シミュレーションの統合に関する研究や、SAC/TD3 のアルゴリズム提案論文(Haarnoja et al. 2018, Fujimoto et al. 2018)が次に読むべき候補である。
Unmanned aerial vehicles (UAVs), particularly quadcopters, present unique challenges for autonomous control due to their underactuated dynamics: only four available control inputs must govern six degrees of freedom. This paper investigates a physics-aware, end-to-end deep reinforcement learning (DRL) approach that acts directly on low-level body inputs, total thrust and body torques $(T, \tau_x, \tau_y, \tau_z)$, and closes the loop through a high-fidelity Simulink environment. Our simulator integrates a 12-state rigid-body model (MATLAB Level-2 S-Function) with (i) an Action2RPM allocation based on the Moore-Penrose pseudo-inverse of a coefficient matrix derived from thrust and drag terms, and (ii) first-order actuator dynamics for each motor (time constant $T_m = 0.076$ s), including rotor gyroscopic coupling. A shaped reward balances goal-reaching and stability using an exponential position well, attitude penalties, and quadratic velocity costs. Four DRL algorithms, DDPG, TD3, PPO, and SAC, are evaluated in two stages: (S1) thrust-only hover and (S2) hover with pitch torque and a translated goal. Results show that SAC and TD3 achieve superior stability and exploration efficiency, while PPO is less sample-efficient. The study highlights the significance of modeling actuator lags and aerodynamic moments for stable low-level control and provides a reproducible benchmark for quadcopter DRL.
