DFIG-Based Wind Turbine Robust Control Using High-Order Sliding Modes and a High Gain Observer
نویسندگان
چکیده
This paper deals with the power generation control in variable speed wind turbines. In this context, a control strategy is proposed to ensure power extraction optimization of a DFIGbased wind turbine. The proposed control strategy combines an MPPT using a high gain observer and second-order sliding mode for the DFIG control. This strategy presents attractive features such as chattering-free behavior, finite reaching time, robustness and unmodeled dynamics (generator and turbine). The overall strategy has been validated on a 1.5-MW three-blade wind turbine using the NREL wind turbine simulator FAST. Copyright © 2011 Praise Worthy Prize S.r.l. All rights reserved.
