The invention discloses a control method and device for the rotating speed of a stern shaft and a storage medium, and relates to the technical field of ship power. The control method is used for controlling the rotating speed of a stern shaft and comprises the steps that the first rotating speed of the stern shaft is determined; determining a second rotating speed of the stern shaft based on a pre-constructed rotor thermal stress model; based on the first rotating speed and the second rotating speed, acquiring a rotating speed reference value and a rate change range of the stern shaft; and controlling the rotating speed of the stern shaft based on the rotating speed reference value and the rate change range. Therefore, the first rotating speed and the theoretical second rotating speed are combined to obtain the rotating speed reference value at the current moment, and the second rotating speed of the stern shaft is combined to obtain the speed change range, so that the change of the first rotating speed is controlled according to the rotating speed reference value in the speed change range, and the rotating speed rapid tracking instruction is realized; and the maneuvering performance and the operation stability of the ship are improved.

    本申请公开了一种船艉轴转速的控制方法、装置及存储介质,涉及船舶动力技术领域。用于控制船艉轴转速,控制方法包括:确定船艉轴的第一转速;基于预先构建的转子热应力模型,确定船艉轴的第二转速;基于第一转速和第二转速,获取转速参考值以及船艉轴的速率变化范围;基于转速参考值和速率变化范围,控制船艉轴转速。如此,本申请结合第一转速和理论上的第二转速,获取当前时刻的转速参考值,同时结合船艉轴的第二转速获取速率变化范围,从而在速率变化范围内,根据转速参考值控制第一转速的变化,实现转速快速跟踪指令,提升船舶的机动性能和运行平稳性。
