Methodology For Robust Control Of Pressure For ε-Caprolactone Polymerization in a Twin Screw Extruder
Keywords:Identification, Reactive extrusion, Robust control
AbstractIn this paper we present a control system based on robust control, which was developed for the regulation of the pressure gradient at the output of a die. In addition, to model the dynamics of the process, we have chosen a second order model with dead time and the identification of dynamical parameters is performed by using the Marquard-Levenberg optimization method. However, to cover the entire range of operation, we were forced to consider two models. The results of the simulation obtained with the robust control are satisfactory.
