Abstract :
Two control strategies are described and contrasted for globally stabilizing ANCBI linear plants subject to input constraints in the presence of persistent, arbitrarily large but bounded, disturbances. The first technique is based on a weaker concept of robust positive invariance, referred to in the paper as positive quasi d-invariance. The second method is based on the classic concept of positive d-invariance.
