Abstract
In this paper we study robustness and sensitivity properties of a samp led-data feedback system with a generalized sampled-data hold function (GSHF), We argue that shifting nonminimum phase zeros using GSHF cont rol can lead to difficulties unless the zero is outside the closed-loo p bandwidth.
