| Abstract: | The paper presented the application of learning control for molding process of electrohydraulic servo injection molding machine (IMM). An anticipatory iterative learning controller was designed and simulated using the model developed. The controller consists of feedforward control and feedback control, and a filter is designed to enhance the robustness of the control system. The proposed control strategy was simulated in the servo injection molding machine, and the experimental investigations demonstrate that the proposed control strategy is effective to track the prescribed trajectory and can improve the repetitive precision of injection molding process. |
