To solve system parameter variation such as magnetic circuit saturation and excitation inductance of the doubly fed induction generator (DFIG) caused by grid voltage swells, a high‐voltage ride‐through (HVRT) robust control method for the DFIG based on the internal model control (IMC) controller is proposed. Through an analysis of the transient behavior of the rotor current caused by grid voltage swells, it was found that a rotor current inner loop using IMC could be established. Utilizing the H2‐norm control theory, and by considering the system's robust stability and robust tracking, the IMC controller parameter of the rotor current inner loop is set. The proposed method suppresses the rotor current and the electromagnetic torque when the parameter changes. Through the simulation of a 1.5‐MW DFIG, it is verified that the proposed method can enhance its HVRT capability, exhibiting good robustness against model errors and external disturbances. © 2018 Institute of Electrical Engineers of Japan.
