PLC在减摇鳍数字化改造中的应用

介绍了PLC 应用于某舰艇减摇鳍系统数字化改造。建立了以PLC 为核心的数字控制
系统，在不增加任何输入信号的情况下，实现原有控制系统的各项功能。此数字控制系统与以数字阀为核心的数字液压随动系统结合，简化了减摇鳍系统结构，提高了系统可靠性。改造后的数字化减摇鳍系统已在某型舰艇上成功投入使用。

Abstract：Applications of PLC in digital renovation of fin stabilizer are introduced. The
PLC-based digital control system is set up, realizing all the functions of previous control system without adding any more input signals. The renovated fin stabilizer system include the PLC-based digital control system and digital valve based the digital hydraulic servo system, which helps to simplify the structure and to uprate reliability of the fin stabilizer system. The developed digital fin stabilizer system has been applied in certain naval ship successfully.
