An Adaptive FLC-GAFOPI Controller for WRSG Based Wind Turbine

This paper deals with design of an adaptive fuzzy logic control-genetic algorithm fractional order-proportional and integral (AFLC-GAFOPI) for a wound rotor synchronous generator (WRSG), based on a variable speed wind energy conversion system (WECS), for improving its power output quality . The AFLC-GAFOPI represents a hybridization of two GAFOPI and AFLC controllers respectively. The first one is designed to upgrade the performance of the system . The second one is chosen to overcome the nonlinearity of the system. To demonstrate the efficiency of the AFLC-GAFOPI controller, a comparison with the GAFOPI controller was performed for different wind regimes. The outcomes clearly demonstrate that the designed controller outperforms the compared controller in terms of response, robustness and overshoot
