The　intelligent　development　of　a　contactor　has　taken　an　increasingly　high　proportion　in　the　electrical　power　system.　In　order　to　adapt　to　the　high-speed　and　complex　real-time　control　strategy,　the　rapid　control　prototype　technology　based　on　single-board　RIO　controller　is　introduced　into　the　multi-intelligent　control　system　of　a　contactor　in　this　paper.　The　double　closed-loop　control　structure　of　the　flux　linkage　and　current　is　adopted　in　the　making　process　of　the　contactor,　so　that　the　coil　current　can　be　adjusted　naturally　in　terms　of　the　air　gap　between　the　cores,　effectively　reducing　the　energy　loss　and　inhibiting　the　contact　bounces.　In　the　closing　process,　a　simple　and　single　current　closed-loop　control　is　adopted.　And　then,　the　contactor　is　demagnetized　at　a　full　negative　voltage.　The　hardware　platform　of　the　embedded　system　based　on　single-board　RIO　is　built,　including　the　driving　module　and　the　data　acquisition　module.　The　system　uses　the　LabVIEW　software　platform　as　the　upper　computer　and　carries　out　real-time　control　of　the　contactor　according　to　the　calculation　of　the　acquired　signal　by　the　FPGA　module　of　the　single-board　controller,　which　verifies　the　control　strategy　designed　in　this　paper.　It　provides　an　efficient　research　and　platform　for　the　development　of　more　complex　intelligent　control　technology　of　contactors.　©　2022,　The　Author(s),　under　exclusive　license　to　Springer　Nature　Singapore　Pte　Ltd.
