Direct　torque　control　(DTC)　strategy　for　multi-phase　drive　based　on　switch　vector　table　has　many　disadvantages,　such　as　the　large　scale　of　the　switch　vector　table,　the　switch　vector　can　not　keep　optimal,　et　al.　Therefore,　a　predictive　DTC　strategy　based　on　voltage　vector　with　zero　zero-sequence　voltage　was　built　in　synchronous　rotating　coordinate　system　of　two　motors　to　realize　the　accurate　decoupling　control　of　electromagnetic　torque　of　two　motors.　In　order　to　further　reduce　the　zero-sequence　current,　the　action　time　of　zero　voltage　vector　and　the　nonzero　voltage　vectors　21　or　42　was　adjusted　by　the　zero-sequence　current　loop.　The　experimental　results　show　that　compared　with　DTC　based　on　switch　vector　table,　the　predictive　DTC　drive　system　proposed　in　this　paper　has　a　large　reduction　in　torque　ripple　and　current　ripple,　and　the　zero-sequence　current　is　well　near　zero.　©　2018　Chin.　Soc.　for　Elec.　Eng.
