Motor　driving　system　is　a　key　technology　for　electric　vehicle　(EV),　and　brake　energy　feedback　technology　which　benefits　to　prolong　driving　rang　is　typical　feature　of　electric　vehicle　driving　system.　Hardware　logic　realization　of　permanent　magnet　synchronous　motor　(PMSM)　driving　control　algorithm　for　EV　in　some　sense　contributes　to　the　integration　of　EV　controller.　This　paper　mainly　researches　on　vector　control　and　energy　feedback　algorithm　for　PMSM,　constructs　digital　high　performance　algorithm　test　platform　for　low　power　PMSM,　and　completes　driving　control　of　PMSM　based　on　this　platform.　©　(2012)　Trans　Tech　Publications,　Switzerland.
