Abstract
In recent years, wind energy has become an important part of the electrical power generation, however, the wind variations produce mechanical power fluctuations and, consequently, the speed changes in the turbine rotor lead to variations in the currents and voltages produced by the wind generators. The purpose of this paper is the set-point regulation of the voltage produced by a main synchronous generator of a wind turbine via the control of a rectified voltage produced by a secondary synchronous generator. The procedure based on the adaptive tuning functions and the backstepping design permits to obtain a nonlinear controller capable of carrying out the control goal for wind variations around nominal values in plants with a uncertainty on the real parameters values.
