为能有效研究数字液压减摇鳍装置,开发了由仿真计算机、可编程控制器(PLC)、数字液压随动机构等构成的半实物仿真系统。该系统采用M atlab编制了风浪及船舶横摇运动的仿真程序,在LabVIEW中设计了运动控制器与人机交互界面,实现了数字液压减摇鳍的计算机半实物控制,得到了理想的控制参数和减摇效果。结果表明:系统人机界面友好,控制参数修改简便,仿真度高,对数字液压减摇鳍实际设计与应用具有较强的理论指导意义。

In order to investigate the digital hydraulic fin stabilizer effectively,a semi-physical simulation system of digital hydraulic fin stabilizer was developed,which consist of simulation computer,PLC and digital hydraulic servo system.The wind-wave and ship rolling simulation was programmed in Matlab,the motion controller and man-machine interface were designed in LabVIEW.The control of digital hydraulic fin stabilizer was realized,and the controlling roll was carried into effect using the ideal control parameter.The experiment shows that the system has a convenient interface,easily amended parameters and has reached high level of simulation,which supply perfect theory reference to the actual designing and applying of digital hydraulic fin stabilizer
