Modeling and Simulation for Vector Control System of PMSM based on SVPWM

In order to improve the operation precision of PMSM and solve the low-usage of bus voltage problem when use the traditional way of SPWM in motor control,this paper introduces the principle of the space vector pulse width modulation(SVPWM) and recommend the manner of its fulfillment.The double-closed loop model is built with vector control based on SVPWM,which is under Matlab/Simulink condition.The simulation results verify the effectiveness of this model and offer useful data for the actual design of PMSM control system.
