On the output feedback control of a synchronous generator

In this article, we propose an output feedback regulation scheme for the electrical angle trajectory tracking in a synchronous generator. Exploiting the flatness of the system we obtain a trajectory tracking error linearizing feedback controller which depends on the available output and its time derivatives. Using a variant of a recently introduced signal time derivative estimation approach based on the "algebraic derivative method", we demonstrate, through computer simulations the effectiveness of our method even in the presence of computer generated stochastic perturbations affecting the dynamics of the system and the available measurements.
