| 摘 要： | 为了得到较高纯度的二甲基甲酰胺（ DMF ），针对DMF回收系统参数特性，提出一种压力、流量的单闭环控制系统和精馏塔串级温度控制方案。单闭环控制系统由上位机、PLC、压力传感器、流量计和电动阀组成。精馏塔温度串级控制系统中，主环是模糊自适应PID温度控制，副环是常规PI流量控制。现场测试及仿真结果表明， FM355 C闭环控制和模糊自适应PID串级控制具有良好的稳定性、响应快和超调量小的特性。

| Abstract: | In order to obtain dimethyl formamide （ DMF） of high purity , based on the parameter characteristics of DMF recovery system , a kind of single closed -loop control system of pressure ,flow and a cascade temperature control scheme of distillation column were proposed .The single closed-loop control system consists of PC , PLC control block , pressure sensor , flow meters and electrically operated valve .In cascade temperature control scheme of distillation column , the main control loop is based on fuzzy adaptive PID temperature control , and the secondary control loop is a flow controller based on conventional PI .Field test and the simulation results showed that FM355 C closed-loop system and fuzzy adaptive PID cascade controller have good stability , fast response and small overshot . |
