%X For the grid side converter, this paper proposes a higher-order sliding mode control(SMC) plus a transient power feedforward PI control to deal with the grid failure and to keep the direct current(DC) voltage stable. Firstly, we analyze the structure and control principle of the double pulse width module(PWM) converter in double-fed induction generator(DFIG). According to the mathematical model of the grid side converter, the paper adopts the voltage orientation vector control principle to realize the unity-power-factor for the alternating current(AC) side and the voltage control in the DC loop. The proposed method speeds up the system tracking, and stabilizes the system under the influence of the external disturbances. Simulation results validate the accuracy and effectiveness of the control strategy proposed in this paper.
