As　the　basis　of　maglev　technology,　a　single-freedom　suspension　ball　control　system　with　hybrid　electromagnets　is　introduced　in　this　paper.　According　to　the　physical　model　of　the　system　we　designed,　the　linear　model　and　control　strategy　were　established　and　analyzed.　A　fixed-point　digital　signal　processor　TMS320F2812　is　chosen　as　the　controller　of　the　system　for　its　high　speed　and　high　efficiency　of　calculation　and　control.　A/D　module　and　the　EventManager(EV)　module　are　used　in　the　system.　PID　algorithm　that　is　applied　frequently　in　industry　is　adopted　and　DSP＇s　output　signal-PWM　signal　is　used　to　control　the　driver.　Both　the　simulation　by　MATLAB　and　actual　control　results　show　the　magnet　suspension　system　works　well.　Copyright　©　(2008)　by　the　Electromagnetics　Academy.
