This article focuses on the figure of the garden in a selection of novels and urban chronicles by José Donoso. A study of these works reveals that the garden fosters the legibility of subjects and urban landscapes within a space of power where aesthetic and political discourses confront each other/are debated. The figure of the garden emerges as a milestone in a written and urban landscape that attracts the vigilant gaze of strategists and the communal aspirations of dissidents.

In this research, a sliding mode regulator with sine mapping is suggested for the stabilization of electricity generators being affected by magnet interaction nonlinearities and generator nonlinearities. To reach this goal, our suggested regulator has the following contributions: it starts from the sliding mode regulator with the modifications that the saturation mapping is used to reach a smoother performance instead of the signum mapping, and the sine mapping is applied to reach an upper bound in the proportional gain error, it (...) is used to reach some chosen constant behaviors for the angle position, angle speed, and current in the electricity generators, and its stabilization is ensured based on the Lyapunov approach. We show the simulation of the suggested regulator in two electricity generators. (shrink)
