摘要 针对丙烯精馏塔,结合模型预测控制器的设计,提出基于系统稳态模型的自适应模型预测控制策略,利用稳态模型在不同操作点上被控变量对操纵变量及扰动变量的相对变化率的变化,来刷新调整预测模型各通道的增益,以有效提高对丙烯塔塔顶、塔底温度控制的性能。现场应用表明:采用该模型自适应调整方法,其控制温度的波动性降低了一个数量级,有利于产品质量的稳定。 Combined with the design of model predictive controller for propylene rectifier,the model adaptive predictive control strategy based on system steady model is proposed. By the relative sensitivity variation of controlled variables to manipulated variables and disturbance variables based on the system steady model, the channel's gain of transfer functions are modified, in order to improve the controlling performance of top temperature and bottom temperature of propylene rectifier. The results of online application show that the variations of controlled temperature are decreased one level by using this strategy, and the product quality is improved.
