Due to factors such as wind variability and randomness

the power output of wind turbines remains unstable. When the wind speed exceeds the rated wind speed

the stability of the wind power generator’s output power is guaranteed by precisely regulating the pitch angle of the blades. In relation to this issue

a wind turbine pitch control model is built by Matlab/Simulink

and a whale algorithm-optimized fuzzy PID controller is introduced. However

there are many parameters of fuzzy controller

and it is difficult to set up by expert experience alone. Therefore

using the whale algorithm

and achieving optimal tuning of fuzzy parameters

effectively addressing the wind turbine’s significant hysteresis and nonlinearity. Comparing the performance metrics of the PID controller and the fuzzy PID controller

and the simulations results show that the latter ensures rapid power convergence to rated values

enhances system dynamic response

and offers precise pitch angle adjustments. Moreover

the fuzzy PID controller precision minimizes pitch mechanism fatigue

and extends the wind turbine’s lifespan.
