Abstract
The aim of this paper is to solve the control problem of trajectory tracking of Autonomous Underwater Vehicles (AUVs) through using and improving deep reinforcement learning (DRL). The deep reinforcement learning of an underwater motion control system is composed of two neural networks: one network selects action and the other evaluates whether the selected action is accurate, and they modify themselves through a deep deterministic policy gradient(DDPG). These two neural networks are made up of multiple fully connected layers. Based on theories and simulations, this algorithm is more accurate than traditional PID control in solving the trajectory tracking of AUV in complex curves to a certain precision.
