We propose a reinforcement learning-based model predictive control method for trajectory tracking of surface vessels. The method utilizes an MPC controller to perform real-time trajectory tracking and control allocation, while simultaneously optimizing closed loop performance through reinforcement learning and system identification. Simulation and sea trial results on two different vessels demonstrate that the proposed method outperforms state-of-the-art methods in terms of tracking performance and energy efficiency.
We present a reinforcement learning-based (RL) model predictive control (MPC) method for trajectory tracking of surface vessels. The proposed method uses an MPC controller in order to perform both trajectory tracking and control allocation in real-time, while simultaneously learning to optimize the closed loop performance by using RL and system identification (SYSID) in order to tune the controller parameters. The efficiency of the method is evaluated by performing simulations on the unmanned surface vehicle (USV) ReVolt, as well as simulations and sea trials on the autonomous urban passengers ferry milliAmpere. Our results demonstrate that the proposed method is able to outperform other state of the art methods both in tracking performance, as well as energy efficiency.
