用闭环增益成形算法的精馏塔鲁棒控制

给出了MIMO系统的闭环增益成形算法，将之应用于精馏塔的控制中，取得了良好的控制效果和鲁棒稳定性。文献［6］给出的回路成形控制器与本文的一阶闭环增益成形控制效果相同，文献［6］评价该法的不足之处是闭环系统的鲁棒性能稍差，该缺点可用本文的二阶或三阶闭环增益成形控制器加以克服。该算法的优点是设计过程简单，物理意义明显。

Robust Control of a High Purity Distillation Column Using Closed-Loop Gain Shaping Algorithm

In this paper, a closed*.loop gain shaping algorithm for MIMO system is presented. It is applied to a high purity distillation column, good control effect and robust stability are obtained. The control effect of a loop shaping controller given in reference [6] is similar to that of the first order controller of closed*.loop gain shaping algorithm, its dissatisfactory robust performance can be improved by using the second or the third order controllers of closed*.loop gain shaping algorithm. The algorithm given in the paper has the advantages of simple design procedure and obvious physical sense.;
