Description: 带搅拌釜式反应器是一种最为常见，具有代表性的反应器，广泛的应用于化工生产的各个领域。带搅拌釜式反应器有一些非常重要的过程参数，如：反应压力、反应温度、冷却水阀流量等等。对于这些参数的控制至关重要，它们不但决定着产品的质量和生产的效率，也很大程度上决定了生产过程的安全性。由于非线性和温度滞后等很多因素，使得常规方法对釜式反应器的控制效果不是很理想。本文以带搅拌釜式反应器的工业生产过程作为被控对象，结合模糊 PID 控制、变比值控制、串级控制、前馈控制等多种控制方式，设计了一套基于西门子 PCS7 的自动化控制系统。-With stirred tank reactor is one of the most common reactor representative, widely used in various areas of chemical production. With stirred tank reactor have some very important process parameters, such as: reaction pressure, reaction temperature, cooling flow valve and so on. For the control of these parameters is essential that they not only determine the product quality and production efficiency, but also to a large extent determines the safety of the production process. Non-linear and as a result of many factors such as temperature lag, the conventional method of autoclave reactor control is not very satisfactory results. Of this article with a stirred tank reactor as the process of industrial production plant, combined with fuzzy PID control, variable ratio control, cascade control, feedforward control and other control methods, design a set of automation based on Siemens PCS7 control system .

Description: 经验设计法简介 梯形图程序设计是可编程控制器应用中最关键的问题 ,PLC 梯形图程序设计常用方法有 : 经验设计法、顺序控制设计法和逻辑代数设计法等。
PLC 梯形图程序用“经验设计法”编写 , 是沿用了设计继电器电路图的方法来设计梯形图 , 即在某些典型电路的基础上 , 根据被控对象对控制系统的具体要求 , 不断地修改和完善梯形图。有时需要多次反复地进行调试和修改梯形图 , 不断地增加中间编程元件和辅助触点 , 最后才能得到一个较为满意的结果。因此 , 所谓的经验设计法是指利用已经的经验 ( 一些典型的控制程序、控制方法等 ), 对其进行重新组合或改造 , 再经过多次反复修改 , 最终得出符合要求的控制程序。
这种设计方法没有普遍的规律可以遵循 , 具有很大的试探性和随意性 , 最后的结果也不是唯一的 , 设计所用的时间、设计质量与设计者的经验有很大的关系 , 因此有人就称这种设计方法为经验设计法 , 它是其他设计方法的基础 , 用于较简单的梯形图程序设计。
用经验设计法编程 , 可归纳为以下四个步骤 :

Sometimes repeated many times to debug and modify the ladder, continue to increase in the middle of programming components and auxiliary contacts, and finally to get a more satisfactory results. Therefore, the so-called experience design is the use of the experience (some typical control procedures, control procedures, etc.), their re-combination or transformation, and then repeated after several modifications in order to work out the control procedures to mee Platform: |
