摘要

为获得高浓度的乙醇精馏，设计了一种比例-积分-导数(PID)控制器。通过对不同数学模型的对比分析，找到了精馏塔第一板温度控制的最优模型。采用计算优化方法设计PID控制器，并在S7-1200可编程控制器上实现。并对乙醇精馏塔的操作进行了评价。

An Automatic Control System Using the S7-1200 Programmable Logic Controller for the Ethanol Rectification Process

A proportional–integral–derivative (PID) controller for ethanol rectification in an eight-section column was developed to obtain a high-concentration product. A comparative analysis among different mathematical models was conducted to find an optimal model to control the temperature of a rectification column’s first plate. The PID controller was designed using a computational optimization method and implemented on an S7-1200 programmable logic controller. Furthermore, the operation in the ethanol rectification column was evaluated.
