A improved Super-twistingl sliding mode （STSMC） direct power control （DPC） is presented to improve the robustness and immunity to interference of the direct power control of a Doubly-fed induction generator （DFIG）. Firstly, the Doubly-fed induction generator model with stator field orientation and the DFIG maximum power capture model under parametric regimes are created; Following that, the Non-singular fast terminal sliding mode surface （NFTSM） and an enhanced Super-twisting optimization method are combined to create the DFIG direct power controller （IST-NFTSMC）. They include the developed Non-singular sliding mode surface, which can successfully avoid the singularity phenomena of conventional sliding mode control （SMC）, and the improved Super-twisting control law, which can successfully reduce the jitter of the NFTSMC and increase the accuracy of the power control; Finally, through simulation and experiment, it is found that compared to the PI control and the conventional sliding mode control, the IST-NFTSMC may reduce the DFIG power and current jitter problem, speed up its convergence, and increase the steady state accuracy of the DFIG direct power management through simulation and experimentation.
