Abstarct: Fractional order control help designer to minimize the modeling error of plants by using more accurate models for systems. By employing fractional order principles, a controller with higher performances for processing control in comparison to integer order controllers will be build. In this thesis the main purpose is to capture the maxium amount of power by1KW vertical axis wind turbine which is produced in Sun Air Research center of Ferdowsi of Mashhad. Fractional order modeling for Buck converter is done and in the following the fractional PID controller which is capable to remove high frequency niose and reject low frequency disturbance along robustness of gain changing in order to achive maximum power from wind. In the past, fuzzy and adaptive methods for inner and outer loops were employed to match with different regions of wind operation. In this research all mentioned constraints and desired performans are satisfied by two fractional PID controllers with constant and non variant gains which are designed in inner and outer loops.
