Abstract

Abstract The development of a robust control system for a variable speed wind turbine (VSWT) is presented in this paper. The proposed controller is designed for torque and pitch control of VSWT operation based on the uncertainty estimator and output feedback for the extraction of utmost power from the wind. A suitable reference model has been obtained for smooth tracking of rotor speed and estimating the uncertainty. The simulation study has been made to show the efficacy of the robust controller designed for VSWT. The performance of the proposed controller has been analyzed by a comparative evaluation with the standard controllers of the wind turbines in terms of the degree of rotor speed tracking, elimination of the effect of uncertainties, maximum power extraction, etc. It is found that the performance of the VSWT operation using the proposed control scheme has been improved significantly in comparison to a few existing control schemes.
