Aiming at the existing problems of the DFIG grid side converter, this paper studies its control technology and proposes a composite control strategy which includes a terminal sliding mode variable structure control of the current inner-loop and a PI controller of the voltage outer-loop in grid side converter. The simulation results show that the control strategy proposed in this paper can achieve better control of the inverter output voltage and input current. What's more important, this method can not only reduce the adverse effects on the grid side converter due to parameter variations and other factors, but also increases the robustness of the system. It has important actual significance and practical application value.
