Abstract:Wind turbine based on Doubly-Fed Induction Generator (DFIG) is gaining in the growing wind market. This paper describes a design method for the fight control of doubly-fed induction generator (DFIG) based on fuzzy sliding mode control, based on the coupling of the fuzzy logic control and sliding mode control. This technique is defined on general, yet detailed. To ensure this requirement a detailed decoupled modeling of DFIG is presented. The relationship between the control parameters and the desired active and reactive power is provided and tested. The main goal achieved by the control strategy is to control the amount of active and reactive power produced by the doubly fed induction generator and injected in the main grid according to the power references derived from turbine's mechanical power and the grid operator. The results of simulation are conducted to validate the theory and indicate that the control performance of the DFIG is satisfactory and the proposed fuzzy sliding mode control (FSMC) can achieve favorable tracking performance.
