摘要

本文主要係探討射出速度自動調整伺服控制器在伺服閥控制射出成型機之實際應用，此技術可大量減少使用不同模具及塑膠材料時之人工調整工作。射出速度自動調整伺服控制器的主要目的係使射出成型機射出單元的螺桿速度可由電液伺服閥配合閉迴路控制之自動調整技術執行控制。由模擬結果知，本文所發展之自動調整伺服控制器可吻合實際實驗性能，而實驗結果更顯示此控制器性能優於傳統PID控制器。

This paper is about the practical application of the autotuning servo controller of injection speed for the servovalve controlled injection molding machine. The manual tuning work for the various resin and mold can be mostly reduced by this technique. The purpose of this controller is that the injection speed of the injection unit in the injection molding machine can be controlled by a servovalve in the molding process by the autotuning closed loop control theory. The simulation results show this controller predition adequately agrees with the experimental data and the experimental results also have shown the autotuning servo controller is superior to the convensional PID controller.
