CONTROL SYSTEM DESIGN FOR GRID SIDE AND MACHINE SIDE CONVERTERS

The purpose of the rotor side converter is to control the rotor currents such that the rotor flux position is optimally oriented with respect to stator flux in order that the desired torque is developed at the shaft of the machine.
The grid side converter aims to regulate the voltage of the dc bus capacitor.
It is allowed to generate or absorb reactive power for voltage support requirements.
In this scheme the control inputs of the system are Urd, Urq to control real/reactive power of the rotor and Ugd, Ugq to adjust the dc-link voltage and injected reactive power to the system.
