Injection velocity control using 2D model predictive iterative learning algorithm

As a typical batch process, injection molding has the following unique features compared to traditional continuous processes: repeatability, two-dimensional dynamics and stages based operations. A sophisticated control algorithm shall exploit all these features. In this paper, a systematic two-dimensional model predictive iterative learning control algorithm is introduced to control the injection molding process with the injection velocity as an application example. The experimental results prove that the control algorithm has good performance and robustness
