In this work, a robust nonlinear control technique of a doubly fed induction generator (DFIG) intended for wind energy systems has been proposed. The principal idea in this article is to decouple the active and reactive power of the DFIG with high robustness using the backstepping strategy. The principle of this control method is based on the Lyapunov function, in order to guarantee the global asymptotic stability of the system. Finally, we present some simulation results in order to verify the efficiency and robustness of the proposed control technique.

  • The backstepping technique combines the notion of Control Lyapunov Function (CLF) with a recursive design procedure. This overcomes the dimension obstacle and exploits design flexibility in the scalar case to solve control problems for higher-order systems.
  • In backstepping design, no constraint is imposed on the nonlinear characteristic of the system.
  • The effectiveness of the backstepping technique is manifest in the presence of parametric uncertainties of the system.
