Gain scheduling control for wind energy conversion optimization

This paper analyzes the variability of the linearized model of a Horizontal Axis Wind Turbine (HAWT) system that operates around the optimal regimes characteristic (ORC). Based on the obtained results, a gain scheduling control structure is proposed for rotational speed tracking in order to ensure maximum power conversion. The proposed control law performances are illustrated by numerical simulation and compared with those of a classical PI control loop that provides optimal wind energy conversion.
