碩士 === 國立臺灣大學 === 電機工程學研究所 === 90 === In this thesis, we propose a novel planar MagLev positioning system, which consists of a carrier with eight permanent magnets embedded and a platform with eight coils, and every magnet is associated with a coil to form a pair. In this system, the levitation forces result from four magnet-coil pairs among them whereas the stabilizing forces are contributed by the other four pairs. Then, the mathematical system model with complete 6 DOFs (degree-of freedoms) is detailedly derived, based on which a PID and an adaptive controller are designed to regulate the six DOFs to a precision extent. In the numerical simulations, good performance can be observed after appropriate control set-up of the above kinds. Finally, satisfactory performance of precision positioning motion can be obtained in the actual experiment. The hereby developed MagLev planar positioning system is novel in that it can provide planar dual-axis motion capability which involves only pure magnetic forces. Functionally, such mechanism behaviors just like a planar XY table with high precision.
