Adaptive Fuzzy-PID Based Pitch Angle Control of Wind Turbine

Abstract

Extracting the maximum energy generated from wind turbines and maintaining their value within the safe limits is the most requesting goal for the wind energy conversion systems. Different traditional control techniques were accomplished to achieve this goal. In this study, the Adaptive fuzzy-PID (AF-PID) controller is applied to control the complex nonlinear system wherever the disturbances have a significant effect on the control efficiency. Moreover, this study proposes an auto-tuning adaptive fuzzy-PID (AF-PID) control method. In addition, the blade pitch angle (BPA) control through self-tuning the parameters, under various working conditions, is the main goal. The simulation outcomes are enclosed whose prove the effectiveness of the auto-tuning adaptive fuzzy-PID (AF-PID) controller in maintaining the output power at rated value above the rated wind speed. MATLAB/SIMULINK is utilized to verify the suggested control technique.
