Pitch control of wind turbine blades in noisy and unstable wind conditions

In this paper, a new approach for control of the pitch angle of the wind turbine is represented in an unstable and noisy circumstance. Moreover, it is demonstrated that output power of the wind turbine can be efficiently controlled by the proposed control system. This method enhances (amends) the stability of the wind turbine. Besides, it improves the regulation of the output power. Also, a comparative study of the proposed control system with a constant pitch angle wind turbines is depicted. For modeling, real data of the wind turbine, model V74 Vestats, and noisy wind model of Manjil area is used.
