In　this　article,　a　double　closed-loop　control　structure　of　a　contactor　is　proposed　for　the　first　time,　in　which　the　outer　flux　linkage　loop　controls　the　inner　current　loop　to　retain　the　merits　of　current　closed-loop　control　while　avoiding　its　defects.　A　voltage　integral　flux　linkage　observer　is　designed　in　the　making　process　of　the　contactor.　In　the　closing　process　of　the　contactor,　the　state　space　expression　of　the　contactor　is　given,　and　the　closed-loop　flux　linkage　observer　is　formed　by　reconstructing　the　flux　linkage　variable.　The　observed　flux　linkage　is　used　as　the　closed-loop　return　signal　to　realize　flux　linkage　closed-loop　control　of　the　contactor　in　the　making　and　closing　processes.　This　control　scheme　can　realize　self-adjustment　of　the　coil　current;　thus,　contact　bounces　are　inhibited.　Meanwhile,　whether　the　movable　core　is　closed　in　place　is　judged　according　to　the　proportional　relationship　between　the　flux　linkage　and　the　coil　current　in　the　closing　process.　Finally,　the　feasibility　of　the　proposed　scheme　is　verified　by　simulation　and　experiment.　©　1982-2012　IEEE.
