A recursive estimator based on the well known least-squares method is used in the identification stage of the proposed controller. The stage for calculation of the signal control method is performed with the Generalized Predictive Controller (GPC) algorithm. The experimental evaluation was performed using step perturbations applied in different operating conditions of the studied power system. For comparison purposes, the results of the evaluation of a self-tuning controller using the pole-placement method for the control signal formulation and three digital controllers with fixed parameters also will be presented.porAcesso AbertoControle de sistema de potênciaControle adaptativoControle preditivoEstimação recursivaArtigo de Periódico
