Abstract :
Studies robustness and sensitivity properties of a sampled-data feedback system with a generalized sampled-data hold function (GSHF). The authors argue that shifting nonminimum phase zeros using GSHF control can lead to robustness difficulties unless the zero is outside the closed loop bandwidth
