Abstract

To improve the running precision of permanent magnet synchronous motor (PMSM) and solve the lower busbar voltage utilization ratio of sinusoidal pulse width modulation (PWM) technique in motor control, the author introduced the principle and realization method of space vector PWM (SVPWM) and applied SVPWM technology under the MATLAB/Simulink to construct the double closed-loop vector control model of PMSM. The simulation results verified the effectiveness of the system design and provided the effective basis for the design of the practical PMSM control system.
