When　a　single-phase　open　fault　occurs　in　five-phase　permanent　magnet　synchronous　motor,　there　is　a　coupling　term　between　the　speed　loop　and　the　current　loop.　It　is　difficult　to　suppress　the　coupling　term　by　using　the　predictive　current　control　strategy　with　the　conventional　cascade　structure,　which　results　in　speed　and　torque　fluctuations　and　a　reduction　of　anti-interference　ability.　Here,　an　integrated　speed　predictive　control　strategy　combining　speed　loop　with　current　loop　is　proposed　to　suppress　the　coupling　term.　When　the　motor　is　in　fault　of　single-phase　open,　the　mathematical　model　is　derived　by　the　coordinate　transformation　matrix　in　the　α-β　coordinate.　It　is　discretized　into　the　speed　predictive　model　by　Taylor　series.　The　fault-tolerant　current　is　calculated　by　the　constraint　condition　of　the　minimum　stator　copper　loss.　Moreover,　the　cost　function　is　designed　with　the　speed　and　current　error　term,　and　the　optimal　voltage　vector　is　determined　to　switch　the　inverter　by　the　minimum　of　the　cost　function　among　the　all　basic　voltage　vectors.　The　simulation　results　show　that　the　proposed　control　strategy　can　reduce　the　errors　in　the　speed　and　torque　for　the　motor　system　and　improve　an　anti-interference　ability　by　comparing　with　the　conventional　strategy.　©　2019,　ICIC　International.
