【摘要】：化工反应釜在化工生产中应用比较广泛,而且在反应釜中的控制方式也是多种多样,尤其是对PID的各种控制方式的应用,所以研究化工反应釜对于过程控制的研究具有很好借鉴意义。本文中所搭建的化工反应釜仿真系统是基于PCS7软件来实现的,PCS7软件凭借其强大的功能能够把被控对象通过CFC块来实现,对于控制方法的应用同样也由CFC块来实现编程,通过SFC顺序控制功能来实现自动控制。在此仿真系统中分为三部分,工程师站、操作员站、自动化站,工程师站进行硬件的组态和控制程序的编写和被控对象的仿真,在操作员站上进行图形对象的设计以及数据归档的设计。工程师站和操作员站通过工业以太网和自动化站通讯。在控制方法上选择了PID控制方式中比较常用的比值控制、分程控制和串级控制,PID的控值参数使用PID Tuner参数整定工具来整定获取。由于现场的被控对象比较复杂,具有大惯性、大滞后环节,难以通过系统辨识的方式来获取,在本文中只能通过查阅资料来获取被控对象的数学模型。
[Abstract]:The chemical reaction kettle is widely used in chemical production, and the control mode in the reactor is also various, especially for the application of various control methods of PID. Therefore, the study of chemical reactor for the study of process control has a good reference significance. The simulation system of chemical reactor built in this paper is based on PCS7 software. With its powerful function, the controlled object can be realized by CFC block, and the application of control method is also programmed by CFC block. Automatic control is realized by SFC sequence control function. The simulation system is divided into three parts: engineer station, operator station, automation station, engineer station, hardware configuration and control program, and simulation of controlled object. Design graphic objects and data archiving on operator station. Engineer stations and operator stations communicate with automation stations via industrial Ethernet. In the control method, the ratio control, which is commonly used in the PID control mode, is selected. The control parameters of the pid are obtained by using the PID Tuner parameter setting tool. Because the controlled objects in the field are complex, have large inertia and lag link, it is difficult to obtain by the way of system identification. In this paper, the mathematical model of the controlled object can only be obtained by consulting the data.
