An intelligent self-tuning fuzzy logic controller for pitch angle control for a wind turbine fed induction generator

This paper, a new strategy for pitch angle control for a Wind Turbine fed Induction Generator (WTFIG) is proposed and simulated. The pitch angle varies according to the wind speed and the output power equation of the entire wind turbine system depends on the pitch angle of a wind turbine. In this paper, an intelligent Self-Tuning Pitch Angle Fuzzy Logic Controller (STPAFLC) is proposed for pitch angle control for a wind turbine fed induction generator. Also, strategies like PI, Pitch Angle Fuzzy Logic Controller for (PAFLC) are discussed to evaluate the performance of self-tuning fuzzy controller. The STPAFLC has been developed and simulated using MATLAB-Simulink and its results are compared with conventional control strategy for WTFIG.
