The work presented in this paper aims to highlight new solutions that improve the performance and reliability of wind turbine systems based on a DFIG. Direct power control using hysteresis regulators in power control laws has many disadvantages, for example, variable frequency and ripple in control variable. To overcome these problems, the trend of current research has been carried out in the field of controls of robust nonlinear systems which give acceptable results in large operating domains. We present backstepping using SVM. A comparative study based on the simulation results is presented, thus making it possible to judge the robustness of the control in each case and for the different operating regimes of the DFIG; these results reflect the good performance of this method and which can be improved the system performance.
