摘要：

In　order　to　realize　the　levitation　control　of　the　globe　with　the　hybrid-excited　magnets,　the　authors　study　the　working　principle　and　the　mathematical　model　of　the　system　by　the　methods　of　the　mechanics　analysis　and　theoretical　calculation　and　obtain　parameters　based　on　experiments.　According　to　the　data　the　author　deduce　the　transfer　functions　of　the　controlled　globe　and　system.　The　authors　utilize　a　PDF　(Pseudo-Derivative-Feedback)　control　arithmetic　to　design　the　PDF　controller.　The　authors　also　analyses　the　systemic　stability,　robustness　and　the　control　precision.　The　study　shows　the　PDF　control　method　is　predominant　in　the　engineering　application　to　the　nonlinear　and　instable　system.　The　method　posses　the　characteristics　of　robustness　and　high　control　precision.　Copyright　©　(2008)　by　the　Electromagnetics　Academy.
