The majority of wind turbines currently in operation have the conventional concept design. That is a single-rotor wind … turbine (SRWT) which is connected through spur gearbox to a generator. Recently, dual-rotor wind turbine (DRWT) has been …

The output power of a wind energy conversion system (WECS) is maximized if the wind rotor is driven at an optimal … measurements of the wind speed and rotor speed. To obtain the optimal operating point, rotor-generator characteristics should be … of wind speed and wind rotor inertia. This issue is analyzed in the paper, and an Adaptive Filter together with a Fuzzy …
