The embodiment of the invention provides a rotating speed control method for a ship water jet propulsion system, which comprises the following steps of: 1, calculating the shortest loading time of the water jet propulsion system according to the loading capacity of a prime mover; 2, calculating a rotating speed increment limit value of a next control period according to the rotating speed instruction of the current control period; and step 3, the rotating speed increment limit value and the rotating speed increment of the original control period are reduced, and a rotating speed instruction of the next control period is generated. The problem that a ship acceleration instruction curve with the high requirement for maneuverability is not matched with the loading capacity of a prime motor is solved. Only instructions are adjusted, internal rotating speed closed-loop control logic of a prime motor (during mechanical propulsion) or a propulsion motor (during electric propulsion) is not involved, and a remote control system can be achieved conveniently. The normal acceleration and deceleration process is not influenced, and the control is performed according to a preset rotating speed instruction curve and only when the loading rate of a prime motor is too high.
本发明实施例提供了一种船舶喷水推进系统的转速控制方法,包括:步骤一:根据原动机加载能力,计算喷水推进系统最短加载时间;步骤二:根据当前控制周期的转速指令,计算下一控制周期的转速增量限值;步骤三:对转速增量限值和原控制周期转速增量取小,生成下一控制周期的转速指令。其解决对机动性要求较高的船舶加速指令曲线与原动机加载能力不匹配问题;其只对指令进行调整,不涉及原动机(机械推进时)或推进电机(电力推进时)内部转速闭环控制逻辑,便于遥控系统实现;不影响正常加减速过程按预先设定转速指令曲线控制,只在原动机加载速率过快时发挥作用。
