摘要:

我们提出了一种基于流量的控制策略,使资源受限的海洋机器人巡逻的回旋状流环境中的轨道轨迹在给定范围内的周期性。控制器不需要流场的详细模型,仅依赖于机器人相对于环流中心的位置。机器人的任务不是精确地跟踪预定义的轨迹,而是停留在具有已知周期性的两个边界轨迹之间。此外,所提出的策略利用周围的流场,以尽量减少控制工作。我们证明了所提出的策略,使机器人在满足所需的周期性要求的流程周期。我们的方法进行了测试和验证,在模拟和实验中使用低成本,欠驱动,表面游泳机器人,即Modboat。

英文摘要:

We present a flow-based control strategy that enables resource-constrained marine robots to patrol gyre-like flow environments on an orbital trajectory with a periodicity in a given range. The controller does not require a detailed model of the flow field and relies only on the robot's location relative to the center of the gyre. Instead of precisely tracking a pre-defined trajectory, the robots are tasked to stay in between two bounding trajectories with known periodicity. Furthermore, the proposed strategy leverages the surrounding flow field to minimize control effort. We prove that the proposed strategy enables robots to cycle in the flow satisfying the desired periodicity requirements. Our method is tested and validated both in simulation and in experiments using a low-cost, underactuated, surface swimming robot, i.e. the Modboat.
