Abstract: This paper proposes a strategy for designing pitch, yaw and supervisory control of wind turbine including a 3D modeling of the whole system. The system is considered here to avoid mechanical losses as well as maintain a constant rotor speed in wind turbine. The wind speed will be varying from time to time, so to protect the turbine from any kind of damage due to wind speed variation, the pitch control system is designed. The direction of nacelle is also varying with time to capture the maximum energy from the air, a yaw control system is
