介紹了PLC 應(yīng)用于某艦艇減搖鰭系統(tǒng)數(shù)字化改造。建立了以PLC 為核心的數(shù)字控制
系統(tǒng)，在不增加任何輸入信號的情況下，實現(xiàn)原有控制系統(tǒng)的各項功能。此數(shù)字控制系統(tǒng)與以數(shù)字閥為核心的數(shù)字液壓隨動系統(tǒng)結(jié)合，簡化了減搖鰭系統(tǒng)結(jié)構(gòu)，提高了系統(tǒng)可靠性。改造后的數(shù)字化減搖鰭系統(tǒng)已在某型艦艇上成功投入使用。

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.
Keywords：fin stabilizer; PLC; digital valve
