عنوان المقالة:نموذج بسيط ووحدة تحكم PI لتحسين خصائص أداء PMSM تحت التحكم الميداني باستخدام SVPWM Simple Model and PI Controller to Improve the Performance Characteristics of PMSM under Field Oriented Control with Using SVPWM
Voltage source inverter is widely used in many
industrial applications such as robot, electric vehicle and machine
tool. The performance of the drive system depends upon the
method of control for converter and motor control method. From
the most performance method is a space vector pulse width
modulation technique. Here the field oriented control of
permanent magnet synchronous motor with using space vector
modulation is used to controlling the inverter and improving the
performance characteristics of the motor such as speed, currents
and the electric torque by reducing their ripples. This occurs
through adding PI controller for flux and simple model to track
the torque and speed when varying load is applied. In the PI
controller, the d-axis flux is compared to rotor permanent magnet
flux to solve the problem arises from non-sinusoidal of the
magnetic flux. The output of the PI controller is added to the
reference d-axis current. The new d-axis current will reach the
best value of THD. The simple model is used to generate new q
axis torque current controller comes from lookup table and
adding to reference q axis current controller to control the motor
speed. The effect of improvement can be seen through the torque
ripples, THD and motor speed. This work is simulated by matlab
simulink.
