射出機為產業界大量使用的生產機械，其特點為可量產高精度、外型美觀及幾何形狀複雜的產品，射出成形過程大致分為烘料、填充、保壓及冷卻四大過程。射出機分為油壓機及全電機，於油壓機方面使用油壓系統驅動螺桿或柱塞進行填充及、保壓等製造過程，因油壓系統為非線性系統，使用PID控制器常造成響應多有過衝現象，穩態表現不佳及壓力目標改變時無法快速響應之缺點，本文內容主要為使用自適性模糊PID控制器以改善上述缺點。

本文包含五個章節，依序為緒論、實驗系統介紹，控制律介紹、壓力控制實驗，最後部分為結論與未來展望。第一章內容包括前言、研究動機、研究方法及文獻回顧，第二章節內容為實驗架構、實驗硬體介紹及實驗硬體動作流程，第三章節則介紹PID控制器、模糊控制器及自適性模糊PID控制器，第四章節為實驗結果，其內容包括油壓響應結果及控制器性能量化指標，最後第五章節為結論與未來展望。

Injection molding machines play important roles in modern manufacture. With the demand of high quantity and quality in production, injection molding machines are commonly used equipments for manufacturing a wide variety of commodity and high technology goods. Traditional injection molding machines with electric motors operating under constant rotating speed consume a large amount of energy. Therefore, energy-efficiency has become a big issue for future injection molding machines. To solve low energy efficiency problems, it is not satisfyied by only using constant rotating speed motor to drive fixed displacement pump as a power source in injection molding machines. To improve the energy-efficiency performance in injection molding machines, there are two ways for energy conservations. Using servo motor to drive pump is possible. Therefore, A hydraulic experiment hardware using a servo motor as the power source to drive was set up. However, the performance of the servo hydraulic system still needs to meet high quality control requirements, thus an adaptive fuzzy PID controller is tested to check the whether it can meet the performance.
