Simulation of PMSM field-oriented control based on SVPWM

Abstract

Aiming at the nonlinear and multivariable complex systems of permanent magnet synchronous motor, a magnetic field oriented control strategy based on SVPWM permanent magnet synchronous motor is proposed. The space vector PWM has the character of wide linear range, little higher harmonic and easy digital realization. The FOC theory and SVPWM technique make the PMSM can achieve the performance as well as DC motor. The mathematical model of PMSM is analyzed and the system model of FOC vector control has been established. The control system has been also simulated by MATLAB/Simulink. The simulation results accord with the real motor's performance and provide the theory basis for the designing of real system.
