sliding mode with neural network regulator for dfig using two-level npwm strategy

This article presents a sliding mode control (smc) with artificial neural network (ann) regulator for the doubly fed induction generator (dfig) using two-level neural pulse width modulation (npwm) technique. the proposed control scheme of the dfig-based wind turbine system (wts) combines the advantages of smc control and ann regulator. the reaching conditions, robustness and stability of the system with the proposed control are guaranteed. the smc method which is insensitive to uncertainties, including parameter variations and external disturbances in the whole control process. finally, the smc control with neural network regulator (nsmc) is used to control the stator reactive and a stator active power of a dfig supplied by the npwm strategy and confirms the validity of the proposed approach. results of simulations containing tests of robustness and tracking tests are presented.
