Simulation of Vector Control Strategy of PMSM Based on MATLAB

Abstract:

In the fields of numerical control machine, robot etc, vector control system of permanent magnet synchronous motor (PMSM) has widely application prospects. Proportion integration (PI) adjustment block, coordinate transformation block, space vector pulse width module (SVPWM) block and the simulation model of the whole system are built in MATLAB/SIMULINK according to the mathematical model, SVPWM technique and vector control theory of PMSM. The simulation results show that stator winding triphase current can run smoothly, speed and output torque can be accurately follow the given value. The results provide the basis for further research of the performance of the PMSM control system.
