Field Oriented Control of PMSM Using SVPWM Technique

3 Abstract: The principle of space vector pulse width modulation (SVPWM) was introduced and implementing for PMSM. Applying SVPWM technique to the PMSM and obtaining the speed, torque, current responses when load was increased. The mathematical model of PMSM is analyzed by neglecting the saturation of the electric motor ferrite core, turbulent flow and hysteresis loss in electric motor. Assuming that the current in the electric motor is symmetrical three phase sinusoidal current and the system model of FOC vector control has-been established. The control system has been simulated by MATLAB/SIMULINK. Simulation results show that the model is effective, and the method provides a frame of reference for software and hardware designs
