四效蒸发器系统的稳定化控制

Stabilization Control of Fourstages Evaporator System

论述了四效蒸发器系统的稳定化控制，采用基于相关系数辨识法的ＰＩＤ自动整定软件，优化整定了丙烯腈装置四效蒸发器系统的所有常规ＰＩＤ控制器参数，达到了使系统平稳运行的目的，取得了很好的控制效果。

The stabilization control of fourstages evaporator system is discussed.Adopting PID autotuning software based on correction coefficient identification approach,all PID controller parameters of fourstages evaporator system in an acrylonitrile plant are optimum tuned,resulting in system stable operation and good control effects.
