This paper deals with the control strategy of wind turbine as the energy transformation takes place from kinetic energy to electrical power. Wind turbine bears different types of loads and this loads can cause vibration and fatigue in blades and cause degradation of blades of wind turbine and these loads can be reduced by better understanding of wind loads and characteristics of wind and design a fuzzy logic control system for the pitch angle. In this paper an advanced pitch angle control system has been designed based on fuzzy logic control system. As the wind speed is having nonlinear characteristics this fuzzy logic controller can compensate this nonlinear characteristics of the pitch angle to wind speed. A conventional PID controller has also been introduced in the model as used in conventional systems and the comparison of both the control system has been analyzed by the simulation results.
