专题 PLC在仿生鱼鳍随动系统中的应用 摘要：减摇鳍是最为行之有效的一种主动式船舶减摇装置，它的减摇效率高，经过６０多年的发展，已广泛应用于各种船舶中。它的减摇原理是：船舶在水中行驶过程中，当鳍在水中有一个速度和倾斜角的时候，就会产生一个升力，利用此升力产生的力矩来抵抗海浪的干扰力矩，便可达到减小船舶横摇的目的。随着科学技术的发展，减摇鳍系统正在逐步完善，减摇效果也在不断提高。 近年来，在工业生产的自动化控制领域中，正普遍利用一种新型控制设备--可编程控制器(ＰＬＣ)。目前的ＰＬＣ正在向着精度更高、功能更多、使用更方便的方向发展。从ＰＬＣ的发展趋势来看，ＰＬＣ控制技术将成为今后工业自动化的主要手段。将其引入减摇鳍控制系统中，实现数字化控制，将进一步提高控制系统的灵活性和可靠性。 关键词：减摇鳍 模拟量 随动系统 Summary: Reduce to shake fin is most for go of valid of a kind of active type ships reduce to shake device, it reduces to shake an efficiency high, through the development of more than 60 years, already extensively applied in various ships.Its reducing to shake principle BE: The ships drives process in the water in, be the fin has a speed and angle of bank in the water of time, will produce a rise dint, making use of this dint that rises the dint creation to resist the interference dint of the wave, can attain to let up ships then horizontal shake of purpose. Along with science technical development, reduce to shake the fin system just at gradually perfect, reduce to shake result also Be raising continuously. In recent years, in the automation control realm of the industrial production, just widespread make use of a kind of new control equipments-programmable controller(the ＰＬＣ ).The current ＰＬＣ is higher just in the facing accuracy, the function is more, usage more convenient direction development. See from the development trend of the ＰＬＣ , the ＰＬＣ control technique will become from now on the main means of the industrial automation. Lead it in to reduce to shake the fin control system in, carry out numeral to turn a control, will raise the vivid and the credibility of control the system further. Keyword: Reduce to shake fin emulation quantity with move system １. 减摇鳍随动系统的构成及工作原理 减摇鳍的随动系统连接来自控制系统的控制信号，是转鳍机构的中间转换和功率放大环节。改造前，每个随动系统由±１５Ｖ稳压电源板ＤＹＣＪ、综合放大板ＳＫＣＪ、操纵转换板ＳＣＣＪ、液压控制系统以用转鳍机构、反馈、限位元件等组成。随动系统应尽可能"快速、准确、稳定"地工作。目前，大多数减摇鳍的随动系统都是"电－液随动系统"。本系统以ＮＪ４型减摇鳍的阀控式电液随动系统为原型，对其做了适当的改进，下面进行详细介绍。 原有随动系统的工作原理图如图１所示。首先将来自控
