Abstract

Tracking control of nonlinear systems subject to constraints on the input is a challenging issue in control design.Forcing saturation on a previously designed controller may in general lead to destabilizationor at least result in performance losses. Hereby it is shown that for a certain class of nonlinear monotone systems it is possible to design a suitable static nonlinear output feedback which stabilizes the system and preserves stability under control saturation.
