Blade pitch angle control of wind turbine based ANFIS controller

The need for energy has become a primary need and requires the stability of electrical energy generation. In a wind turbine system, a special control is needed to keep the turbine rotation at a certain limit. However, in reality, load conditions often fluctuate due to an increase or decrease in load. Therefore, the purpose of this research is to design an ANFIS controller to control blade pitch angel with adaptive changes in wind speed and load dynamics, and the testing is done through simulation on Simulink/MATLAB. The controller works to adjust the blade angle when the generator speed exceeds/less than the set point value due to changes in wind turbine speed and load dynamics. By adjusting the rotor speed of the generator, the output power delivered can be balanced with the use of the load, which is indicated by the output frequency value being stable at 50 Hz. From the ANFIS controller testing process through simulation, it can be concluded that the ANFIS controller generator can maintain the output frequency with load dynamics due to the presence of a more controlled pitch angle control than the Fuzzy-PID controller by decreasing up to 1,454% overshoot and 6,26s settling time.
