Robust adaptive Backstepping control approach of DFIG generators for wind turbines variable-speed

In this paper, we present a nonlinear robust control of active and reactive power by the use of the technique Backstepping a double-fed asynchronous generator (DFIG) system incorporated in a wind. The power transfer between the stator and the network is carried out by acting on the rotor via a bidirectional signal converter. A new control technique for wind systems is presented. This control system is based on an adaptive pole placement control approach integrated to a Backstepping control system. The stability of the system is shown using Lyapunov technique. The performances and robustness of DFIG and wind-turbine are analyzed and compared by simulation based Matlab / Simulink software.
