Control of a twin wind turbines system without wind velocity information

This paper proposes a new control scheme for a non-standard wind turbines system, that comprises two identical wind turbines and has no yaw actuator to ensure the alignment face to the wind. Furthermore, the controller based on super-twisting algorithm is a sensorless one, in the sense that it does not require wind speed measurement. Such feature is attained thanks to the use of a very recent differentiation approach. The performance of the proposed controller is assessed by simulation.
