摘　　要：置换蒸煮是一种新型节能、环保的溶解浆间歇蒸煮方式,蒸煮质量更好。通过分析溶解浆置换蒸煮不同工艺过程的控制策略,针对蒸煮锅锅内温差时滞性、实时性等特点,设计了DMC-PID串级控制器。通过Matalab仿真结果表明,DMC-PID串级控制器在超调量、动态响应方面控制效果更好,同时也具有较好的抗干扰。Displaceent Digester System（DDS） is a new style of energy-saving and environment protective batch di-gester in dissolving pulp production. By the reasearch on control strategy of different technologies of dissolving pulp＇ s Displacement Digester System, the DMC-PID controller was designed according to the range of temperature having a character of delaying, time delaying. The DMC-PID controller has no overmodulation and good dynamic responce according to the result of Matalab simulation. At the same time the DMC-PID has strong capability of anti-disturb-ance.
