Aiming　at　the　problems　of　overshoot,　weak　disturbance　resistance　ability　and　poor　adaptive　ability　of　permanent　magnet　synchronous　motor　using　PI　control　algorithm.　Firstly,　the　field　oriented　control　(FOC)　model　of　permanent　magnet　synchronous　motor　is　analyzed.　Secondly,　based　on　the　active　disturbance　rejection　control　and　fuzzy　control　principle,　the　speed　loop　controller　is　improved,　and　the　fuzzy　active　disturbance　rejection　control　algorithm　is　designed.　The　control　algorithm　preserves　the　advantages　of　active　disturbance　rejection　control,　and　realizes　the　online　tuning　function　of　active　disturbance　rejection　control　parameters,　which　improves　the　adaptive　ability　of　the　system.　Finally,　the　simulation　experiment　is　carried　out　on　the　MATLAB　/　Simulink　platform,　and　the　results　show　that　the　fuzzy　active　disturbance　rejection　control　algorithm　has　the　characteristics　of　no　overshoot,　high　control　accuracy　and　strong　adaptive　ability.
