摘要

本文第一部份係描述伺服閥控制射出成型機之射出速度伺服控制器，並利用Matlab/Simulink軟體繪出全系統數學方塊圖。第二部份則是討論一個新的電腦輔助頻域分析方法，其係在Matlab/Simulink環境下，分析射出速度伺服控制器的頻率響應。最後則是分析探討射出速度伺服控制器的頻寬特性，並針對模擬結果進行討論。

This study used frequency domain to analyses the injection speed servo-control of the injection molding machine. In this paper, the injection speed servo-control system of the injection molding machine is illustrated and described by Matlab/Simulink firstly. Secondly, a new method of frequency domain analysis via the Matlab/Simulink is presented, From the simulation results, the step responses of the injection speed servo-controller was discussed and the control bandwidth of the injection speed can be predicted by the computer-aided method of frequency domain analysis.
