  4. Abstract:
  5. In this research, nonlinear sliding mode pitch control of a wind turbine has been investigated by considering aerodynamic nonlinearities. For modeling aerodynamic interaction between the wind and the drive-train system, blade element momentum theory is used by considering Prandtl's tip loss factor and Glaurt correction. Finally, the two-degrees of freedom model of the drive-train is extracted and the sliding mode approach is examined for regulating the output power into its nominal value by controlling the pitch angle. The implementation of the above proposed control law in its related electronic circuit of the wind turbine will be considered as the future stage of the current research. © 2020 IEEE
