Estimation of Kinetic Parameters of a Polymerization Reactor Using Real Data

Abstract This paper presents the comparison of some method related with the most important steps in the parameter estimation procedure to fit kinetic parameters of an HDPE polymerization reactor using real data from an industrial plant. An identifiability analysis was performed prior to the parameters estimation. For this analysis, two methods for scaling the sensitivity matrix and two methods for parameter screening are considered. This paper also compares the minimizing of the goal functions considering the square error (SE) and the square of the derivative of the error (SDE).
