碩士 === 國立臺灣大學 === 機械工程學研究所 === 89 === The main purpose of the research is to improve VRPT(Variable Resistance Pulse Tube refrigerator) cold-end temperature controller which is designed by Jing-Tun You.We analyze to the control performance further, and expected to improve the performance of the controller.The main point which we want to improve is the response speed .After using the new controller we designed,the response speed improve substantially. Besides,in order to the demand of my research,we write a VRPT monitor and control program.We collect all the function and set up a designed controller on it. The experiment results show that this controller have the outstanding representation in every test.From this we prove that VRPT indeed can use automatic control technology to attain the best operation.
