摘要
针对氯乙酸生产过程中氯化工序与结晶工序的特点及其控制系统性能的要求,我们选择了A-B公司的Control-Logix集成控制系统来构成氯乙酸生产过程控制。控制系统由过程控制级与监控管理级构成,形成二级分层体系结构。并在氯化工序中采用了前馈-串级复合控制,在预热水温度中采用了自适应Smith预估补偿控制。
In this paper,a A-B Company's ControlLog ix system applied in the chloroactic acid mass producing is introduced.According to the requirement of the technic,this system is consisted of the process control level and monitor system level.The paper analyzes the feedforware -cascade control alg orithm of chloroat-ing -caldron inner temperature and circulative Smith predictive control alg orithm of the warm-up water tem-perature in crystalling -procedure.
