Observer-based saturated output feedback control using twisting algorithm

Publikation: Beitrag in Buch/Bericht/KonferenzbandBeitrag in einem KonferenzbandForschungBegutachtung

Abstract

In this paper, second-order systems in the presence of both uncertainties and disturbances are considered. It is revealed that super-twisting controllers based on high-order sliding mode observers cannot be implemented when uncertainties are taken into account. An output feedback control law adopting the twisting algorithm is designed such that a Lipschitz continuous as well as saturated control signal is introduced to the system. In order to illustrate the feasibility and effectiveness of the proposed approach, numerical simulations are employed.
