精馏塔的自适应解耦控制

Adaptive Decoupling Control of a Distillation Column

本文针对某精馏塔提出了一种简单的自适应解耦控制器。该控制器将广义最小方差控制策略和解耦补偿器结合起来,不仅可以对随机多变量系统实现动静态解耦而且具有良好的伺服跟踪性能。该控制器与常规PI控制器在某精馏塔双组分控制中的对比实验结果表明自适应解耦控制的性能优越于常规PI控制。

In this paper,a simple adaptive decoupling controller for a binary distillation column is presented.The controller combines a decoupling compensator with generalized minimum variance control strategy.It can real-lize decoupling for stochastic multivariable systems dynamically and at steady state It also has good trace perfor-mences.Experimental results of adaptive decoupling control and conventional PI control to a binary distillation column show that the performences of adaptive decoupling control are better than those of conventional PI control.
