The invention discloses a hovercraft propulsion pitch control system, and relates to the field of hovercraft control, and the system comprises a plurality of pitch control assemblies which are respectively installed at different control positions of a hovercraft and can work independently; the main controller obtains a pitch control value output by the target pitch control assembly in the current control state as a given pitch, and performs closed-loop control on the propulsion pitch in combination with a pitch feedback value sensed by a pitch sensor mounted at the variable pitch execution mechanism; in addition, the screw pitch manipulating values of other screw pitch manipulating assemblies are controlled to follow the given screw pitch. The system not only can meet the control requirements of different control positions of the hovercraft, but also can reduce the influence of the failure of a single screw pitch control assembly on the control of the whole hovercraft by the plurality of screw pitch control assemblies, thereby improving the reliability, ensuring the stability during the switching of the control states by the follow-up control of different screw pitch control assemblies, and improving the reliability of the hovercraft. And the control complexity of the switching process is reduced.

    本申请公开了一种气垫船推进螺距控制系统,涉及气垫船控制领域,该系统包括分别安装在气垫船的不同操控位处且可以独立工作的多个螺距操纵组件,主控制器获取当前控制状态下的目标螺距操纵组件输出的螺距操纵值作为给定螺距,并结合变距执行机构处安装的螺距感应器感应到的螺距反馈值对推进螺距进行闭环控制,另外还控制其他各个螺距操纵组件的螺距操纵值随动跟随给定螺距。该系统不仅可以满足气垫船不同操控位处的操控需求,且多个螺距操纵组件可以降低单个螺距操纵组件故障给整船控制带来的影响,从而提高可靠性,对不同螺距操纵组件的随动跟随控制保证了控制状态切换时的稳定性,且降低了切换过程的控制复杂度。
