Identification of PWARX Model Based on Outer Bounding Ellipsoid Algorithm

Abstract

This paper concerns the identification of a trans-esterification reactor using PWARX (PieceWise AutoRegressive eXogenous) hybrid systems. The OBE (Outer Bounding Ellipsoid) algorithm is then applied in order to estimate the parameters for each sub-system. This algorithm is used for system identification when bounded disturbances are present. This paper aims to experimentally apply the OBE algorithm to represent the dynamic of a transesterification reactor with PWARX system using real measurements.
