A novel adaptive control scheme for dynamic performance improvement of DFIG-Based wind turbines

Song, Zhanfeng; Shi, Tingna; Xia, Changliang; Chen, Wei - In: Energy 38 (2012) 1, pp. 104-117

A novel adaptive current controller for DFIG-based wind turbines is introduced in this paper. The attractiveness of the proposed strategy results from its ability to actively estimate and actively compensate for the plant dynamics and external disturbances in real time. Thus, the control...
