The redesign of output feedback controllers for linear systems based on adaptive saturation (stubborn) and dead-zone redesign is investigated by showing that input-to-state stability holds in closed loop upon the satisfaction of linear matrix inequalities. Such results are obtained by using sector conditions that are involved in the Lyapunov analysis in order to ensure input-to-state stability. A simulation case study shows the effectiveness of the proposed redesign in denoising and outlier attenuation with increased accuracy and precision.

Abstract
The redesign of output feedback controllers for linear systems based on adaptive saturation (stubborn) and dead-zone redesign is investigated by showing that input-to-state stability holds in closed loop upon the satisfaction of linear matrix inequalities. Such results are obtained by using sector conditions that are involved in the Lyapunov analysis in order to ensure input-to-state stability. A simulation case study shows the effectiveness of the proposed redesign in denoising and outlier attenuation with increased accuracy and precision.File in questo prodotto:
