description The invention discloses a control method for separating isopropyl alcohol/diisopropyl ether/water azeotrope through azeotropic distillation. The control method comprises the following specific design steps: step 1, designing a proportion-integral control strategy for separating isopropyl alcohol/diisopropyl ether/water; and 2, designing a diisopropyl ether/isopropanol/water model prediction control strategy. And 3, designing a soft measurement-based model prediction control strategy of diisopropyl ether/isopropanol/water. The time delay neural network algorithm is used for optimizing model predictive control, the improved model predictive control is combined with a combined control scheme of a proportional-integral controller, the control problems of difficulty in real-time measurement of components, multivariate, strong coupling and the like in the azeotropic distillation process are solved, the dynamic control performance is improved, and the control cost is reduced. According to the control scheme, when th
