摘要：

In　order　to　realize　the　suspending　control　of　the　globe　with　hybrid-excited　magnets,　a　new　control　arithmetic　pseudo-derivative　feedback　(PDF)　was　adopted　for　mechanical　and　kinematic　analyses.　The　mathematical　model　of　the　system　was　established.　The　transferring　functions　of　the　controlled　object　and　the　control　system　were　deduced,　and　its　stability　was　theoretically　analyzed.　The　study　results　show　that　the　PDF　control　solution　has　the　characteristics　of　robustness　and　high　control　precision,　compared　with　the　nonlinear　instability　of　the　hybrid-excited　magnet　system.
