摘要:

在本文中,我们提出了使用基于鲁棒模型预测控制(RMPC)的强化学习(RL)的自主水面车辆(ASV)的控制。RL-MPC策略用于避障和目标(设定点)跟踪。针对船舶推进器可能出现的故障,提出了一种基于神经树的鲁棒预测控制算法。此外,风和海流被认为是未知的随机干扰在实际系统中,这是通过收紧约束处理。通过RL使用Q学习技术来调整紧固和其他成本参数。考虑了经济成本,最大限度地减少了实现船舶任务所需的时间和能量。该方法是在模拟上的一个非线性3自由度模型的比例版本的赛博飞船2。

英文摘要:

In this paper, we present the use of Reinforcement Learning (RL) based on Robust Model Predictive Control (RMPC) for the control of an Autonomous Surface Vehicle (ASV). The RL-MPC strategy is utilized for obstacle avoidance and target (set-point) tracking. A scenario-tree robust MPC is used to handle potential failures of the ship thrusters. Besides, the wind and ocean current are considered as unknown stochastic disturbances in the real system, which are handled via constraints tightening. The tightening and other cost parameters are adjusted by RL, using a Q-learning technique. An economic cost is considered, minimizing the time and energy required to achieve the ship missions. The method is illustrated in simulation on a nonlinear 3-DOF model of a scaled version of the Cybership 2.
