摘要
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。
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.
