摘要
聚合反应釜是聚合反应工程中的重要装置,其运行质量将直接影响到聚合产品的质量和整个生产过程的安全与稳定。根据聚合釜间歇操作的工艺条件不确定性问题提出了采用分段切换控制的方法。该方案在DCS中通过SCX编程语言实现,实际运行结果表明,聚合温度的智能控制系统其稳定情况和温度超调都符合工艺要求。
The characteristics and controlling strategies of the polymerization reaction has been introduced in this paper. According to the uncertainty and non - linear characteristics of control object, a method of using Section -switching control is put forward. The control program is code in SCX based on the DCS. The results show that advance controller of the polymerization temperature is superior to the original PID program, its stability and the temperature overshoot are in line with technological requirements.
