Robust Explicit Moving Horizon Control and Estimation: A Batch Polymerization Case Study

Abstract

This paper focuses on the design and evaluation of a robust explicit moving horizon controller and a robust explicit moving horizon estimator for a batch polymerization process. It is of particular interest since there are currently no reported case studies or implementations of the explicit parametric controller/estimator for batch and polymerization processes. In this paper we aim at achieving tight offset-free tracking of a desired reactor temperature profile, making accurate states estimation despite of the possible perturbations, and demonstrating the practical applicability to a case with industrially relevant complexity.

Robust Calorimetric Estimation of Semi-Continuous and Batch Emulsion Polymerization Systems with Covariance Estimation

“…The proposed method by the authors estimated the particle size distribution and corrected the model in order to fit to the experimental data. Sui et al implemented an explicit MHE for a simulated styrene batch polymerization reactor. The states estimated corresponded to the temperature, volume, and pressure.…”
