Nowadays the search for renewable energy has increased due to the increment in greenhouse gases, due to the increment in hydrocarbon prices and seeks to reduce the costs of electricity generation. The wind turbine becomes importance by allowing to extract the energy from the wind in a clean and renewable way, and convert it into electricity through a generator, which is the reason why all governments seek its development and promote investment in wind farms. In wind turbines like aerogenerators, the best power condition for harvesting the energy is obtained when an optimal rate of the tip blade speed and the wind speed called lambda λ is achieved, which has an important influence on the turbine power and allows to calculate the optimal torque as a set point. The adaptability of the controller proposed in the research is achieved due to the weights that give greater or lesser hierarchy to independent control strategies, each tuned to handle a range of speed and wind acceleration, weights that are calculated by fuzzy logic control techniques. In the presence of abrupt changes in wind speed, strategies that have a higher sampling frequency gain greater value, and in the face of mild winds those with lower frequency increase. A field-oriented torque controller in cascade is used for the generator, regulating the magnetic field and the torque. This research deals with the development of a controller for improving the performance of an induction generator, driven by a wind turbine. Its goal is the modeling, design, and analysis of an algorithm in search for an optimal operating point that improves the extraction of wind energy. For the control algorithm, an adaptive multi-frequency sampling method is presented, with a structure formed by a group of PID controllers, each one with a different sampling time and having a different weight or hierarchy in the torque set maintained by the generator. The research will prove that the multi-frequency sample controller can extract more wind energy compared to a traditional control algorithm such as PID.
