Abstract

This paper addresses the problem of robust controller design for a class of discretetime switching systems with input saturation. To this aim, the composite nonlinear feedback (CNF) method is extended to design a robust controller with improved performances in terms of the response speed and overshoot in the presence of disturbances and input saturation. The proposed approach is theoretically analyzed and its closed-loop stability is proved. Then, the performance of the proposed method is verified using numerical simulations.
