| Abstract: |
| This paper presents an enhanced control strategy for Wind Energy Conversion System (WECS) using Doubly-Fed
Induction Generator (DFIG). A robust Super-Twisting (STW) sliding mode control for variable speed wind turbine is
developed to produce the optimal aerodynamic torque and improve the dynamic performance of the WECS. The
electromagnetic torque of the DFIG is directly tracked using the proposed control to achieve maximum power
extraction. The performance and the effectiveness of the STW control strategy are compared to conventional
Sliding Mode (SM) and Proportional-Integral (PI) controllers. The proposed STW algorithm shows interesting features
in terms of chattering reduction, finite convergence time and robustness against parameters variations and system
disturbances. |
