Abstract

This paper presents an application of fuzzy controllers for improving wind energy capture for variable speed wind turbines. In recent works, it has been shown that variable speed wind turbines with torque and blade-pitch linear control provide an excellent performance of the closed loop system. However, this performance can be enhanced by using fuzzy control. In the present work, a computational fuzzy model is presented for a variable speed, variable pitch wind turbine. Simulation results show an excellent performance improving transition between power optimization and power limitation of the wind turbine, specially in the rated wind speed working conditions
