Direct Field Orientation Control Based on H∞ Method of Wind Turbine Based on DFIG

Abstract

This study aims to propose the direct field orientation control based on the H-infinity method (DFOC_ H_∞) scheme for controlling the stator power (active/ reactive) of a direct drive vertical axis wind turbine power system based on a doubly fed induction generator (DFIG). the sensitivity to parameters uncertainty of the machine presents the major drawback of the PI controller, in order to cope with this problem; the H-infinity method was used to solve it. The proposed controller H_∞ is evaluated with Matlab/Simulink.  Simulation results showed that the suggested H_∞ controller has a good performance in terms of enhancing the quality of energy provided to the power network. Even in the presence of DFIG parameter variation.
