摘要
采用离线分析手动增量ＰＩ反馈控制，在混合澄清槽镧铈分离的两个出口都稳定得到了高于４Ｎ和３Ｎ纯度的产品。作者认为如用ＰＩＤ反馈控制，可提高控制质量。
The off line analysis and finger feedback control for the separation of lanthanum and cerium in multistage mixer settlers have been performed.4N and 3N purity of products was achieved for the outgoing products carried by both the loaded solvent and the aqueous raffinate at both ends. The authors conside that control quality will be improved if PID feedback control is performed
