The control system is a key element when aiming to increase the power generated and therefore the efficiency of wind turbines. Because of the nonlinear dynamics and uncertainties usually present in wind turbines, the efficiency of these systems can be enhanced by employing advanced control schemes. Wind turbine systems are usually constructed using electric generators of variable velocity, such as double-feed induction generators (DFIG), since they may improve the system efficiency in the generation of electric power compared to fixed-speed generators. This is mainly due to the fact that these generators with variable speed may adapt the speed of the turbine thus maintaining the optimal tip speed ratio value, which improves the efficiency of the wind turbine system. However, in these systems, a suitable controller of the turbine velocity is required in order to track the optimal velocity reference that optimizes electric power generation. This Special Issue of Energies aims at addressing the challenges in control design and implementation for wind turbines to convert the wind energy into electrical energy. Original submissions focusing on new control techniques and practical implementation of these new control schemes are welcome. The topics of interest of this Special Issue include, but are not limited to: adaptive control schemes; robust control schemes; sliding mode based control schemes; fuzzy logic based control schemes; neural network based control schemes; observer based control schemes; practical implementation of advanced control schemes; wireless sensors in control schemes.
