To maximize wind energy captured in variable speed wind turbines at low to medium wind speeds, a robust control strategy is presented. The proposed strategy simultaneously controls the blade pitch and tip speed ratio, via the rotor angular speed, to an optimum point at which the efficiency constant (or power coefficient) is maximum. The control method allows for aerodynamic rotor power maximization without the restrictions of exact wind turbine model knowledge. A series of numerical results show that the wind turbine can be controlled to achieve maximum energy capture.

This paper proposes a control strategy to maximize the wind energy captured in a variable speed wind turbine, with a separately excited DC internal generator, at low to medium wind speeds.

All patients were male labors between 22-30 years old, and the amputation due to machine injuries. Successful replantation were achieved, after a period of follow up with occupational therapy all patients regain good functional and cosmetic results. This study proves the strong indication of replantation of multiple digits & hand amputations.
