Dynamic and static modeling of extruder thermodynamics and linear programming of extruder power consumption

In this paper, a new model is developed for the extruder, a traditional industrial production equipment, which contains a thermodynamic model and a kinetic model of the extruder. This paper analyzes the dynamic and steady-state characteristics of the extruder. The new model can reflect the characteristics of the extruder system without excessive complexity, and it is suitable for use in practical control because it integrates the temperature control and power consumption control of the extruder. Finally, the new model was used to simulate the extruder, and the power consumption of the extruder was controlled by linear programming. The effect of the insulation level of the extruder on the power consumption was discussed.
