电力推进的船舶在恶劣海况下航行时存在较大扰动，螺旋桨不断进出水面，使船舶推进电机的转速和转矩过大从而造成机械损耗。为此，本文提出一种针对恶劣海况的船舶电力推进系统抗过旋控制策略，不同于平静海况的转速控制策略，考虑船桨通风状态以及损失的估算，对损失因子和估算转矩进行分析，验证抗过旋控制的可靠性。
A propeller subject to extreme conditions may experience large load transients due to ventilation and in-andout-of water effects. The controllers designed for normal conditions may then no longer give satisfactory performance. Since torque and power control needs keeping constant, a loss of propeller load torque will lead to severe motor racing. To assure satisfactory performance for all conditions, the anti-spin control strategy for extreme conditions is therefore introduced. Differing from control strategy for normal conditions, the ventilation detection and loss effects are included the Anti-Spin control strategy. Moreover, loss factor and torque calculation are analyzed. The reliability of the anti-spin control strategy is verified.
