Adaptive Backstepping control of wind turbine two mass model

A Backstepping adaptive control is proposed in this paper in order to raise the extraction of power in variable speed wind turbine in region two. This wind turbine is modeled by two masses drive-train with generator torque control. By using the model obtained, an algorithm of adaptive Backstepping has been designed to achieve the global asymptotic generator with speed tracking and to estimate the unknown parameter of viscous friction coefficient. A numerical simulation studies are presented to verify the efficiency of this control approach, if we add disturbances to take advantage of this control.
