Real-time application of scheduling quasi-minmax model predictive control to a bench-scale neutralization reactor

Abstract

Scheduling quasi-minmax model predictive control is an MPC algorithm developed by (Lu and Arkun, 2000) initially for linear parameter varying (LPV) system, then developed for nonlinear systems in (Lu and Arkun, 2002). In this paper, real-time application of the scheduling quasi-minmax MPC algorithm onto a bench-scale pH neutralization reactor is presented. The control performance is compared with multi-linear model based MPC modified from the algorithm in (Kwon and Pearson, 1978) and scheduling IMC-PID controller in which tuning parameters are from IMC design in (Morari and Zafiriou, 1989).
