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
