Volume 1, Issue 2 , September 2018, , Pages 103-113

https://doi.org/10.22111/ieco.2018.23895.1023

Abstract
  The paper presents the computer simulation of a multivariate control algorithm. Industrial relevance is given as the problem is derived from a real plant, an industrial athmospheric distillation column at Shiraz refinery. The control performance of the industrial column using relative gain array (RGA) ...  Read More
