    • Current waterjet technology uses hydraulic actuators that are linked to a hydraulic system aboard the vessel. Hydraulic actuators have a significant number of problems including, but not limited to, significant size and weight, poor efficiency, an excessive number of components, excessive heat generation, slop in the feedback system, overshooting of cylinders, limited ramping ability, frequent maintenance, environmental concerns, and difficulty in interfacing with control systems. In an effort to reduce, and in some cases eliminate, these issues, this invention discloses an apparatus and method of controlling a waterjet that uses electric actuators and motor controllers that are integrated on the jet. The use of multiple electric actuators also allows for redundancy, which makes the system more reliable. The system also allows a user to have direct actuator control and bypass the automatic settings for control system backup.
    • 当前的水刀技术使用与船上液压系统相连的液压执行器。 液压执行机构存在相当多的问题,包括但不限于显着的尺寸和重量,效率低下,部件数量过多,产生的热量过多,反馈系统中的斜坡,气缸过冲,限制斜坡能力,频繁维护, 环境问题以及与控制系统接口的困难。 为了减少并在某些情况下消除这些问题,本发明公开了一种控制水射流的设备和方法,该设备和方法使用集成在射流上的电致动器和马达控制器。 使用多个电动执行器还可以实现冗余,从而使系统更加可靠。 该系统还允许用户执行直接的执行器控制并绕过控制系统备份的自动设置。
