Estimator-based control of reactive distillation system: Application of an extended Kalman filtering

A Hybrid FLC-EKF Scheme for Temperature Control of a Refinery Debutanizer Column

“…Now (23) The component balance equation around the reboiler is (24) Similar with the reflux drum holdup, the column base holdup ( ) was also remained very close to constant and, consequently, (24) can be rewritten as (25) Substitution of (25) into (23) gives (26) In discretized form (27) Substituting (27) …”

“…Extended Kalman Filter: The Kalman filter techniques are discussed elsewhere ([10]- [14] and [26]) and the EKF algorithm is presented here in brief. The EKF is computed in two steps.…”

Soft sensor based composition estimation and controller design for an ideal reactive distillation column

“…Venkateswarlu and Jeevan Kumar [10] have presented an inferential state estimation scheme based on an extended Kalman filter (EKF) with optimal selection of sensor locations using principal component analysis (PCA) for composition estimation in multicomponent reactive batch distillation. Olanrewaju and Al-Arfaj [11] have shown that a state estimator (Extended Kalman filter) can be successfully designed and implemented in a feedback control system of reactive distillation. They showed that the estimator-based system is robust against a moderate measurement errors and erroneous initial conditions.…”

ANN based soft sensor model for reactive distillation column

“…While, non-linear method includes artificial neural network (ANN) [7][8][9][10][11][12][13][14][15], and support vector regression (SVR) [5,[16][17][18]. Whereas, [19] and [20] proposed the first soft sensors for online monitoring in reactive distillation column's (RDC). They used extended Kalman Filter approach to estimate the product purity in the column.…”
