| Abstract: | On the basis of analyzing modulation technology in pulse width of space vector of three-level and the mathematics model of PMSM,directional control strategy of rotor magnetic field is used to design a PMSM vector control system based on SVPWM three-level inverter.MATLAB/Simulink simulation software is employed to set up system's simulation model,which synthesizes the PMSM frequency variation velocity modulation,the vector control,the SVPWM technology and three-level inverter.The simulation result indicates that the system can obtain the good dynamic and static performances,showing the advantages of three-level inverter. |
