碩士 === 明新科技大學 === 精密機電工程研究所 === 96 === This research focused on utilizing MATLAB/Simulink to simulate and compare the electro-hydraulic servo control system based on two different design approaches, which are a traditional PID controller design method and logic controller. Through a design of experiments method, analysis of variance (ANOVA) and regression analysis, how the controlled parameters impacts the controller can be evaluated and an optimal parameter setting can be obtained. Furthermore, not only the tracking or positioning performance of a controller can be greatly improved, but also mathematical models are established using the proposed method. Based on the findings, the found fuzzy PD-PI controller and the Neural Network controller utilizing the new designing method yields a better performance than that from the traditional PID controller design technique. In addition, a trial-and-error tuning approach can be eliminated.
