碩士 === 國立中正大學 === 機械工程系研究所 === 105 === Nowadays, the industrial development gradually becomes a trend of automated control and analysis of big data. The content of development included high-accuracy, high-speed and high-efficiency. It’s important that the concept and technology of Maglev push forward the industry 4.0. Also this paper hope that the theory will be hypostatized. There are different advantages of Maglev such as frictionless, long service life and no noise which make the guideway much more excellent than the Linear guideway in this paper. Maybe someday, the magnetic guideway will replace the linear guideway which had been used in the recent. The magnetic guideway in this paper is designed and developed by myself, and the design purpose will make the entire guideway float completely. At the controller's part, I added coils which play an important role in this system. And it's able to push the passive force back to the equilibrium position, so we simulate the size of coils by the Maxwell. Also the passive as important as coils, the significant function of the passive provides the carrying capacity. The Halbach array which through the different arrangement to enhance the magnetic force of the one side and reduce the other side at the same time is a considerable factor. There are five degrees of freedom in the magnetic guideway, and those must allow for the coupling of the whole system. To understand the coupling phenomenon, it was necessary to describe the coordinate of the system dynamics properly by selection and through the corollary, operation of the kinematic equation. In the process of calculation, the passive was thought of instability. However, the passive force is measured in the system by the experiment and it's through the curve fitting to obtain the equation of the force. Eventually, the PID controller was designed to meet the needs of the system, and I can know that whether the system will be able to go back to the equilibrium position by simulation.
