Abstract
A method for automated quality control in film extrusion processes using a production model-based control system. The method involves monitoring quality parameters of produced film and comparing them against target values to determine deviations. Using a production model, the system establishes relationships between these quality deviations and physical operating parameters of the extrusion line. Based on these relationships, the system automatically generates and implements control value adjustments to the relevant physical operating parameters. The adjusted parameters are then used to continue film production, creating a closed-loop control system that maintains product quality. This automated approach enables real-time quality optimization and reduces the need for manual intervention in the film extrusion process.
