摘要:

无人水面车辆技术(USVs)是一个令人兴奋的话题,它基本上是部署一种算法来安全有效地执行任务。尽管强化学习是一种众所周知的建模这种任务的方法,但当结合偏离策略和函数近似时,可能会发生不稳定和发散。在这项工作中,我们使用深度强化学习将Q学习与神经表示相结合,以避免不稳定性。我们的方法使用深度Q学习,并将其与敏捷方法的滚动波规划方法相结合。我们的方法包含两个关键部分,以便在未知环境中执行任务。第一种是路径规划器,负责生成到达目的地的潜在有效路径,而不考虑根的细节。后者是一个决策模块,负责在价值函数的背景下,在不久的将来USV开发步骤中避免障碍物的短期决策。使用两种算法进行模拟:一个基本的香草血管导航仪(VVN)作为基线和一个改进的血管导航仪与计划和局部视图(VNPLV)。实验结果表明,所提出的方法提高了VVN的性能平均为55.31长距离任务。我们的模型通过深度强化学习在未知环境中规划自适应路径,成功地证明了避障。

英文摘要:

Unmanned Surface Vehicles technology (USVs) is an exciting topic that essentially deploys an algorithm to safely and efficiently performs a mission. Although reinforcement learning is a well-known approach to modeling such a task, instability and divergence may occur when combining off-policy and function approximation. In this work, we used deep reinforcement learning combining Q-learning with a neural representation to avoid instability. Our methodology uses deep q-learning and combines it with a rolling wave planning approach on agile methodology. Our method contains two critical parts in order to perform missions in an unknown environment. The first is a path planner that is responsible for generating a potential effective path to a destination without considering the details of the root. The latter is a decision-making module that is responsible for short-term decisions on avoiding obstacles during the near future steps of USV exploitation within the context of the value function. Simulations were performed using two algorithms: a basic vanilla vessel navigator (VVN) as a baseline and an improved one for the vessel navigator with a planner and local view (VNPLV). Experimental results show that the proposed method enhanced the performance of VVN by 55.31 on average for long-distance missions. Our model successfully demonstrated obstacle avoidance by means of deep reinforcement learning using planning adaptive paths in unknown environments.
