中文摘要：

自动控制已广泛应用于现代化工生产,不仅改进了生产装置的自动化水平,而且提高了产品的质量和产量.介绍了一种以生产过程监控软件和PLC（可编程控制器）相结合的方法,对一套乳液聚合装置进行自动控制系统设计,实现了整个生产过程的自动控制以及监控功能.对其中影响质量最关键的因素--聚合温度,采用了串级加分程控制方法进行调节,通过长期实际运行,系统达到了预期设计的控制效果,证明了控制系统的可行性.

英文摘要：

Automatic Control system has been widely used in the field of modern chemical produc tion industry, which not only enhances the automatic level of production device but also elevates products＇ quality and output. A method combining manufacture process monitoring system and PLC is presented, through which automatic control system of a set of device for latex polymerization is developed and automatic control and monitoring function of the whole manufacture process are realized. For the key factor influencing quality best-polymerization temperature, cascade with stroke dividing control algorithm is applied. Through long term practical running, control effect reaches the expectation, which demonstrates the feasibility of this control system.
