Abstract :
This paper describes the experimental application of Nonlinear Model-Predictive Control (NMPC) in conjunction with on-line state and parameter estimation to control a packed distillation column. Due to mass transfer effects, the process gain changes sign within the region of operation, which precludes the use of a linear controller for closed-loop control.
