Optimized fuzzy PI controller for variable speed wind turbine using DE algorithm

To design an optimal fuzzy proportional-integral (PI) controller for the variable speed wind turbine systems, a new differential evolution (DE) algorithm approach is developed in this paper. We have investigated PI controller, which rules are applied to adapt parameters of founded on error and its first-time derivative. The controller's inputs outputs tuned using DE optimization method. superiority suggested (DE PI) has been proved by comparing results with (fuzzy only system. In comparison selected human operator, numerical validation shown good performance terms robustness, pursuit, response time.
