Abstract
Melt temperature and screw rotational speed are important parameters in the injection molding process since they affect other injection molding processing conditions, cycle time and product quality. It has been shown that predictive control provides better close loop process dynamics in comparison to the conventional control in injection molding process. However, the magnitudes of controller parameters were non-optimal, and were generally chosen after several iterations. A simple and effective tuning strategy was developed for predictive control, and was implemented for controlling melt temperature and screw speed. Better temperature and screw speed process control were obtained using this new tuning method. The tuning method also demonstrated good control performance for SISO and MIMO processes control simulation.
