Abstract
  The changes in the crude oil flow rate to an atmospheric distillation unit can influence the quality of the products. This paper presents a modification method for soft sensing model including an update term, which makes it compatible with industrial variations. A modified soft sensing structure is adopted ...  Read More

Volume 2, Issue 2 , April 2019, , Pages 155-166

http://dx.doi.org/10.22111/ieco.2018.26166.1067

Abstract
  In this paper, a novel centralized controller is presented to control multi-input multi-output industrial processes with heavy interactions and significant time-delays. The system model equations are represented in a non-minimal stochastic state-space form. Also, the state and measurement equations respectively ...  Read More

Control Structure Design and Dynamic Modeling for Atmospheric Distillation Column: Effect of Increase Capacity

Mir Mohammad Khalilipour; Farhad Shahraki; Jafar Sadeghi; kiyanoosh Razzaghi

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

http://dx.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
