An Adaptive Fuzzy Tuned PID Pitch Controller For Large VSWT Wind Turbine

Reducing or limiting the turbine’s performance at high wind speeds can be effectively achieved by altering the pitch angle of the blades. Big wind turbines with variable pitch control usually use PID control to maintain a constant output power when wind speeds surpass the rated limit. However, the traditional PID controller finds it difficult to achieve the desired performance due to the daily and hourly fluctuations in wind velocity, which are unpredictable. This is mainly because pitch angle and wind speed exhibit a non-linear association at high wind speeds. This study uses a PID controller tuned by an adaptive fuzzy logic structure (F-PID) to study how power generation is controlled in variable-speed wind turbines (VSWT). To test the effectiveness of the control approach and the system itself, the pitch angle control system was simulated using the MATLAB/Simulink simulation platform. An artificial wind profile was used to test the controller’s effectiveness, and the findings showed that the recommended controllers were indeed successful at controlling power. The suggested controller is compared with the standard PID controller to highlight the improvements of the approach.
