This paper proposes an active steering controller for Driven Independently Rotating Wheelset (DIRW) vehicles based on deep reinforcement learning (DRL). For the two-axle railway equipped with Wheelsets (IRWs), each wheel connected to a wheel-side motor, Ape-X DDPG controller, enhanced version of Deep Deterministic Policy Gradient (DDPG) algorithm, is adopted. Incorporating Distributed Prioritiz...
