标题： Assessing Linear Control Strategies for Zero-Speed Fin Roll Damping

摘要： 滚转稳定是船舶运动控制中的关键方面，特别是在低速或零速条件下运行的船舶，传统水动力鳍失去其有效性。 在本文中，我们考虑由Navis JSC开发的一种滚转阻尼系统，该系统基于两个主动控制的零速鳍。 与传统的鳍式稳定器不同，零速鳍采用阻力机制和主动振荡来在船舶静止时产生稳定力。 我们提出了一种简单的线性控制架构，但同时考虑了非线性阻力和执行器限制。 在用于HIL测试的高保真船舶模型上的仿真结果证明了所提出方法的有效性。 显示英文摘要

摘要： Roll stabilization is a critical aspect of ship motion control, particularly for vessels operating in low-speed or zero-speed conditions, where traditional hydrodynamic fins lose their effectiveness. In this paper, we consider a roll damping system, developed by Navis JSC, based on two actively controlled zero-speed fins. Unlike conventional fin stabilizers, zero-speed fins employ a drag-based mechanism and active oscillations to generate stabilizing forces even when the vessel is stationary. We propose a simple linear control architecture that, however, accounts for nonlinear drag forces and actuator limitations. Simulation results on a high-fidelity vessel model used for HIL testing demonstrate the effectiveness of the proposed approach.
