To　address　the　problems　of　traditional　model　predictive　direct　torque　control　strategy,　such　as　low　computational　efficiency,　high　voltage　jump　and　poor　steady-state　characteristics,　an　improved　model　predictive　direct　torque　control　strategy　is　proposed.　To　improve　the　steady-state　characteristics　of　the　motor,　36　virtual　voltage　vectors　are　constructed　based　on　the　principle　of　the　nearest　three　vectors.　The　action　time　of　redundant　vectors　in　the　virtual　voltage　vector　is　adjusted　by　combining　the　principle　of　no　beat.　To　prevent　excessive　voltage　jump　in　the　output　line　of　the　inverter　from　causing　adverse　effects　on　the　motor,　only　voltage　vectors　with　voltage　jump　not　exceeding　Udc　/　2　are　selected　as　alternative　voltage　vectors.　Meanwhile,　the　reference　voltage　vector　is　predicted　by　combining　the　model　with　the　deadbeat　principle,　and　the　voltage　vector　located　in　the　same　sector　as　the　reference　voltage　vector　is　selected　as　the　final　candidate　vector　set.　Compared　with　traditional　control　strategies　under　rated　operating　conditions,　the　experimental　results　show　that　the　improved　control　strategy　reduces　the　electromagnetic　torque,　stator　flux　amplitude　error,　and　current　harmonic　distortion　rate　by　37.　42%,　32.　00%,　and　44.　52%,　respectively.　The　program　execution　time　is　reduced　by　approximately　11.　52%　.　©　2023　Science　Press.　All　rights　reserved.
