Current Control for DFIG Systems Under Distorted Voltage Using Predictive-Repetitive Control

This article presents a predictive-repetitive control for rotor current control operating under voltage harmonic distortion for a doubly fed induction generator in a synchronous reference frame. Predictive-repetitive control is an approach that uses receding horizon by predictive control with frequency decomposition of the reference signal. Moreover, to apply in wind energy, the predictive-repetitive control is implemented and designed from the perspectives of the power system. This controller is designed by using the state-space model of the plant, and the experimental results with voltage harmonic distortions are presented to prove the proposal.
