Abstract

Sampled-data feedback systems which contain a saturating element are investigated in this paper. A condition which must be satisfied if these systems are to be stable is developed; it is shown that this is a necessary condition for stability and an intuitive argument is presented to indicate that this condition is probably sufficient. Finally, a method to obtain a digital filter for compensating and/or stabilizing these systems is presented.
