The　intelligent　contactor　based　on　current　closed　loop　control　is　commonlyaccepted.　In　order　to　solve　the　disability　of　mechanical　disturbance-resistant　and　beat　delay　problem,　the　active　disturbance　rejection　with　current　model　predictive　control　strategy　is　proposed.　The　mechanism　of　disturbance　to　current　closed　loop　is　analyzed.　The　current　slope　is　observed　under　different　coil　voltage　and　core　velocity.　The　anomaly　of　current　rising　slope　related　to　iron　core　speed　is　proved　to　infer　the　motion　of　iron　core　under　zero　coil　voltage.　The　deadbeat　model　considering　induct　electric　potential　compensation　is　established　to　predict　current　and　eliminate　control　delay.　The　quadratic　evaluation　function　for　rolling　optimization　is　introduced　to　predict　optimum　duty　and　switch　function.　The　switch　function　of　zero　voltage　is　automatically　set　to　observe　current　slope　when　disturbance　happens.　The　current　setpoint　is　adjusted　autonomously　and　the　contactor　has　the　function　of　active　disturbance　rejection.　Besides　diminution　of　current　static　error,　ripple　and　harmonic　are　considered　when　holding.　Related　simulation　and　experiment　prove　the　effectiveness　of　the　proposed　strategy.　The　strategy　particularly　improve　the　holding　stability　of　intelligent　contactor　used　in　new　energy　sector.　©　2018,　Electrical　Technology　Press　Co.　Ltd.　All　right　reserved.
