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.
