FEM based modelling and control of temperature field in extruder barrel

Abstract

In the paper, first a basic concept of the approximation models of distributed parameter systems for modelling and control is introduced. Next, finite element method modelling of temperature field in extruder barrel is demonstrated and finite-dimensional approximation models are created. By means of DPS Blockset for MATLAB & Simulink, feedback system of control and also block scheme for co-simulation joining COMSOL Multiphysics and MATLAB & Simulink software environment are prepared. Finally, after simulation real-time control process of temperature field in extruder barrel is executed.
