Abstract

In this paper, we present a novel nonlinear method using proposed third-order sliding mode command (TOSMC) for the doubly-fed induction generator (DFIG) controlled by direct reactive and active powers command (DRAPC). In the first place, we establish the proposed mathematical models of the proposed TOSMC controller. To regulate the power flowing between the grid and the DFIG, a proposed strategy design uses the proposed TOSMC method is applied for implementing to minimize the torque ripple, reactive and active powers oscillations  on a traditional  DRAPC method. The use of this controller provides very satisfactory effectiveness for the DFIG command, and the chattering effect is also more minimized by this proposed controller. The proposed TOSMC controllers which are insensitive to uncertainties, including parameter modification and external disturbances in the whole command process. Finally, the DRAPC with proposed TOSMC controllers is used to regulate the reactive and active powers of a DFIG-based dual-rotor wind turbine (DRWT) and confirms the validity of the proposed controllers. Results of simulations containing tests of tracking and robustness tests are presented.
