Study above an adaptive control structure with aplication to a double-fed induction generator´s excitation

This paper presents a self-tuning adaptive control structure designed through the minimization of a criteria function. It is described the computation methodology of the control law, being particularized for the case of a dual winding induction generator´s excitation control. The parameter´s estimator, integrated into the control system, is based on the online least mean square error algorithm. In order to validate the designed control structure and tuning, there are performed and presented several study cases.
