This paper uses the sliding mode technique to present a robust nonlinear observer for a two-mass model (2-MM) of variable speed wind turbine (VSWT). A dynamical 2-MM of VSWT, including the effect of uncertainties, is considered for designing the robust sliding mode observer (SMO). The SMO is designed to estimate the states of the VSWT, to help the controller capture the maximum power from the available wind, and alleviate the stress on the wind turbine. Simulation results demonstrate the applied approach's efficacy in robust performance with lesser estimation errors under uncertainties.

摘要

This paper uses the sliding mode technique to present a robust nonlinear observer for a two-mass model (2-MM) of variable speed wind turbine (VSWT). A dynamical 2-MM of VSWT, including the effect of uncertainties, is considered for designing the robust sliding mode observer (SMO). The SMO is designed to estimate the states of the VSWT, to help the controller capture the maximum power from the available wind, and alleviate the stress on the wind turbine. Simulation results demonstrate the applied approach's efficacy in robust performance with lesser estimation errors under uncertainties.
