A Comparative study of FLCTuned PID Controller andConventional PID Controller For The Pitch Control Of Wind Turbine In Turbulent Winds

Abstract

 Adjusting the pitch angle of the blades provides an effective means of regulation or limiting turbine performance in strong wind speeds, in case of above rated wind speed, large scale wind generators with variable pitch control usually uses PID control to maintain its output power constant. However, as the velocity of the wind varies randomly on a daily and hourly basis, the simple PID controller can hardly achieve satisfactory performance, as at high speed, the relationship between pitch angle and wind speed is nonlinear. This research work presents an adaptive F-PID controller for the control of generated power from a variable pitch variable speed wind turbine. Controller performance is evaluated on the MATLAB/SIMULINK platform and compared with the performance of a PID controller. In this study a wind profile is developed by an autoregressive moving average (ARMA) model and the results are validated to show that proposed F-PID controller can effectively regulate the output power of wind turbine in the turbulent wind speeds.
