| Summary: | 碩士 === 國立成功大學 === 機械工程學系專班 === 95 === The trends of design and development of machine tool have been focused on the features of high speed, high precision, and high efficiency. The pneumatic counterweight method is a suitable counterweight method used for machine tool. However, the cylinder force output must be controlled to reduce the disturbance force and to promote the precision of vertical positioning control for spindle feeding. For the reason, the purpose of this study was to analyze the Active Pneumatic Counterweight System on the basis of a mathematical model and the use of Self-tuning Fuzzy Controller (STFC) on servo pneumatic pressure control for cylinder force output. The system was experimented under pressure control at the different travelling rates, and results of this experiment were discussed respectively.
