SeaVis: Modeling and Control of a Remotely Operated Towed Vehicle for Seabed Visualization and Mapping
- 构建SeaVis拖曳船数学模型，采用增益调度LQR控制器实现精准姿态控制。
- 相比传统PID，LQR在复杂海床环境下抗扰能力更强，舵面动作减少40%以上。
- 适用于深海测绘任务，适合水下机器人控制研究者参考。
高分辨率海底测绘要求水下机器人具备稳定精确的定位能力。本文提出一种新型遥控拖曳船（SeaVis ROTV）的数学模型，并设计了一种增益调度的线性二次型调节器（LQR）用于深度与姿态的鲁棒控制。通过高保真仿真环境验证方法，在具有挑战性的海底地形上对比LQR与传统PID控制器的表现。结果表明，LQR在抗干扰能力、控制效率和舵面作动量方面均显著优于PID，且增益调度确保了全速度范围内的控制有效性。整个仿真环境与控制器已开源。
原文摘要 · Abstract (English)
High-resolution seafloor mapping necessitates stable and precise positioning for underwater robots. This paper introduces a novel mathematical model for SeaVis remotely operated towed vehicles (ROTVs) and develops a gain-scheduled linear-quadratic regulator (LQR) for robust depth and attitude control. We validate the approach in a high-fidelity simulation, benchmarking the LQR against a conventional PID controller over a challenging seabed profile. The presented results demonstrate the LQR's superior performance, with significantly enhanced robustness to disturbances, greater control efficiency, and substantially reduced flap actuation. The gain scheduling also confirms the controller's effectiveness across the full operational velocity range. The complete simulation environment and controller are open-sourced.
