Abstract:	現在的社會中，只要提到跟塑膠成品有相關的機器，想必大家第一個都會想到射出成型機，目前最快、最方便也是最普遍的塑膠原料處理機，從工業電子產品到民生必需品如杯子和吊飾等，都是經由射出成型機製造出，而產品的品質則和控制的精準度息息相關。就目前工業技術而言，射出成型機的控制已相當成熟，無論是油壓式或是全電式，都在一定的水準之上，而就目前而言，最大的瓶頸仍然是保壓的部分，由於壓力曲線深深影響著產品的品質好壞，所以壓力的追蹤仍是現在許多人研究的課題，而本篇論文即運用模糊控制與PID控制來做比較，並模擬出兩種控制法則下的射出段保壓表現。 If we talk about the plastic, most people will have an impression on the injection molding machine in the modern society. It is the fastest, most convenient and popular machine to manufacture the plastic products. From the industrial use to people’s daily use, most plastic products are manufactured by the injection molding machine. The quality of the product has relations with the accuracy of the controller. The injection molding technology has already developed for so many years. Whether the all-electric or hydraulic machinery, the performance is up to the standard. Nowadays the major problem about the injection molding machine is tracking the holding pressure profile. The holding pressure profile relates to the quality of the product a lot. In this paper, I use the fuzzy and the PID control law are used and compared to track the pressure profile.
