摘　　要：提出了一种乙醛精制装置的多变量预测控制策略。该策略应用自主开发的多变量预测控制软件将该装置两个精馏塔统一考虑实施多变量预测控制 ,减小了成品塔温度的波动 ,稳定了最终乙醛产品的质量 。A multivariable predictive control strategy on an acetaldehyde distillation units is introduced. The two columns are controlled together by selfdeveloped multivariable model predictive controller software. The variation range of the columns temperature is reduced, and the acetaldehyde quality is stabilized,and also the distillation units operate on the optimal steadystate operating points.
