为了稳定准确控制风帆转角位置,根据所设计的风帆驱动控制液压系统原理,提出风帆转角/速度复合控制方案。利用AMESim-MATLAB/Simulink软件建立风帆转角/速度复合控制联合仿真模型,并进行了联合仿真及实验研究。结果表明:采用复合控制可以克服常规控制中出现的压力波动及启停时的液压冲击;在不同转角速度及不同风力负载条件下,风帆均能按照规划的速度及位移进行转动,体现了复合控制的有效性和可靠性,可以为风帆助航船的风帆控制提供技术支持。
Abstract
In order to stably and accurately control the position of the sail angle, according to the principle of the sail driving control hydraulic system, the integrated coordinated control scheme of the sail angle/speed was proposed. The compound control joint simulation model of the sail angle/speed was established by using AMESim-MATLAB/Simulink software and joint simulation and experimental research were carried out.The results show that the compound control can overcome the pressure fluctuation and hydraulic shocks that occur in conventional control when starting and stopping; under different rotational speed requirements and different load forces, the sail can be controlled according to the planned speed and displacement, which reflects the effectiveness and reliability of the compound control, and can provide technical support for the sail control of the sail assisted ship.
