The invention relates to a dynamic matrix control system of high-purity distillation, which comprises distillation tower, intelligent checker, DCS system, superior host, and on-site bus, while they are connected. The control system uses tower product group as the object variable, and the reflux ratio and reboil ratio as control variable; the superior receives history temperature and pressure data from the DCS real-time database, via the predict control and dynamic matrix controller, to obtain the output values of present controller as reflux ratio and reboil ratio, then feedback said two values to DCS system, to function the distillation object. The invention can confirm the high-purity stable operation, with better dynamical control.

本发明公开了一种高纯精馏的动态矩阵控制系统和方法；系统包括：精馏塔、智能检测仪表、DCS系统、上位机和现场总线；所述精馏塔、智能检测仪表、DCS系统和上位机通过现场总线依次相连，实现信息流的上传和下达；本发明所涉及的控制系统采用塔双端产品组分为被控变量，回流比和再沸比为对应的控制变量；上位机从DCS实时数据库中获得历史的温度、压力等数据，通过推断控制环节和动态矩阵控制器环节，得到当前控制器的输出值-回流比和再沸比，再把控制器输出值返回给DCS系统，实现了对高纯精馏过程的双端产品高纯控制，对双端组分的高纯度平稳操作，具有很好的动态品质和控制效果。
