On the stabilization of linear discrete time systems subject to input saturation

摘要

In this paper, an exponentially unstable linear discrete time system subject to input saturation is shown to be exponentially stabilizable on any compact subset of the constrained asymptotically stabilizable set by a linear periodic variable structure controller. We also point out that any marginally stable system~2 subject to input saturation can be globally asymptotically stabilized via linear feedback.
