基于PLC的液位模糊控制系統(tǒng)設(shè)計(jì)

文章應(yīng)用德國(guó)SIEMENS S7-300 可編程序控制器設(shè)計(jì)一個(gè)兩維模糊控制器，將控制器的模糊輸出反模糊化后化為實(shí)際輸出而控制調(diào)節(jié)閥的開(kāi)度，使中位水箱的液位達(dá)到給定值。通過(guò)在組態(tài)王中的參數(shù)連接與設(shè)置，實(shí)現(xiàn)液位運(yùn)行畫(huà)面的監(jiān)測(cè)。運(yùn)行結(jié)果表明，所設(shè)計(jì)的二維模糊控制器能精確控制中位水箱的液位，獲得了良好的控制效果。

Abstract：This thesis design two dimensional fuzzy controller use the programmed logic controller of Siemens S7-300. Fuzzy output defuzzified physics output which control regulate valve and make the mid tank water level up to the set point. With setting the parameters, the software “Kingview” is used to monitor water level the data. The implementing result proves the fuzzy control for the middle tank is effective.Using empirical control methods to retain a high-quality control system.
