Reducing or limiting the turbine's performance at high wind speeds can be effectively achieved by altering pitch angle of blades. Big turbines with variable control usually use PID to maintain a constant output power when surpass rated limit. However, traditional controller finds it difficult achieve desired due daily and hourly fluctuations in velocity, which are unpredictable. This is mainly because speed exhibit non-linear association speeds. study uses tuned an adaptive fuzzy logic...
