Adaptive predictive control of a distillation column
Tae-Woong Yoon, Dae Ryook Yang, Kwang Soon Lee, Young-Min Kwon
Abstract
Distillation processes reveal complicated multivariable nonlinear dynamics for which it is difficult to design a high-performance control system. This paper proposes an adaptive control scheme for a distillation column. The proposed
adaptive system consists of a multi variable receding-horizon predictive controller using a transfer function model and a recursive least-squares (RLS) based estimator. Simulations show a consistent closed-loop performance despite the
uncertain nonlinear characteristics of the distillation column.
