BACKSTEPPING ADAPTIVE CONTROL OF DFIG- GENERATORS FOR WIND TURBINES VARIABLE-SPEED

In this paper, we present a new contribution for control of wind turbine energy conversion system. A new observer Backstepping control of DFIG-Generators for Wind Turbines Variable-Speed is developed. A new control technique for wind systems is presented. This control scheme is based on an adaptive pole placement control strategy integrated to a Backstepping control scheme. The overall stability of the system is shown using Lyapunov technique. The performance and robustness are analyzed and compared by simulation using Matlab / Simulink software.
