Synthesis of optimal power tracking Pitch angle controller for wind turbines based on fuzzy logic system and dynamic surface control

Abstract

This paper proposes a method to enhance the performance of wind turbin by a fuzzy logic system. The fussy logic system is carried out as an intelligent system in order to determine a desired Pitch angle for each value of wind speech such that the turbin’s power is maximum. To ensure that the Pitch angle can track stably the desired angle, dynamic surface control is developed. The control quality of closed-loop system is analysed and simulated with different scenarios.
