摘　　要：依据我国现行船舶生活污水排放标准与系统控制功能需求,为解决传统控制方法对船舶生活污水控制精度低的问题,文章在分析归纳近海某7500 t散货船所使用的生活污水处理装置的工艺基础上,建立系统曝气装置的数学模型,提出一种基于传统比例积分微分(PID)控制与模糊控制相结合的模糊PID控制算法。基于Beckhoff PLC技术与对象链接与嵌入的过程控制(OPC)通讯接口开发一套基于智能控制策略的船舶生活污水监控系统。仿真结果表明:系统的控制精度提高,排放监测效果良好,系统能稳定运行。According to the current discharge standards for domestic sewage from ships in China and the requirements of the system control function,this study endeavours to solve the problem of the low precision of conventional control methods in controlling domestic sewage from ships.The processes of the device to treat domestic sewage from a 7500-tonnage bulk carrier near the sea are analyzed and summarized.On this basis,a mathematical model of the system aeration device is constructed,and a fuzzy proportional-integral-derivative(PID)control algorithm is proposed by the combination of traditional PID control and fuzzy control.A monitoring system for domestic sewage from ships based on an intelligent control strategy is developed based on the communication interface between the Beckhoff PLC technology and object linking and embedding(OLE)for process control(OPC).The simulations demonstrate that the system features higher control precision,a positive effect of discharge monitoring,and stable operation.
