The Study Of Vector Control Of Permanent Magnet Synchronous Motor

Vector control of PMSM was studied in the paper。 Based on studying the mathematic model of PMSM and the principle of vector control .A emulation model of vector control system of PMSM were built using MATLAB/SIMULINK. After parameter of the model was tuned and good emulation performance was obtained .PWM generation method without zero vectors and fuzzy control of speed loop was emulated and better control effect was obtained.IRMCS2011 is the newest type of servo developing platform, which adopts vector control method. the experiment of motor on the platform proved good performance of vector control.Control structure and principle has expatiated in the paper.The paper also discussed some items corrective to PMSM speed control system, including position servo emulation and the methods of evaluating initial rotor position.All these work clarified the principle, methods and performance of PMSM vector control system. It has reference value for studying PMSM vector control system and improving its performance in the future.
