水下机器人三维路径跟踪与L1自适应控制

3D Path Following and L1 Adaptive Control for Underwater Vehicles

Nicholas Rober, Maxwell Hammond, Venanzio Cichella, Juan E. Martin, Pablo Carrica

摘要:

本文研究水下机器人的制导与控制问题。多级控制策略用于确定(1)外环路径跟随命令和(2)内环致动命令。具体地,视线路径跟踪算法用于引导车辆沿着三维路径,并且$\mathcal{L}_1$自适应控制算法用于确定低级方向舵命令以实现路径跟踪。这些外环和内环控制算法的性能界限。使用基于物理的Simulink模型获得的数值结果被用来帮助可视化的控制算法的性能。

英文摘要:

This paper addresses the problem of guidance and control of underwater vehicles. A multi-level control strategy is used to determine (1) outer-loop path-following commands and (2) inner-loop actuation commands. Specifically, a line-of-sight path-following algorithm is used to guide the vehicle along a three-dimensional path, and an $\mathcal{L}_1$ adaptive control algorithm is used to determine the low-level rudder commands to accomplish path following. The performance bounds of these outer- and inner-loop control algorithms are presented. Numerical results obtained using a physics-based Simulink model are used to aid in visualization of the control algorithm's performance.
