Abstract
An analysis about the limiting zeros of a plant of nominal order at most two under FROH-discretization is presented. The continuous transfer function is decomposed as a sum of a nominal plant plus a disturbance transfer function of any order. A root-locus based analysis is used with the aim of finding the limiting discrete zeros. Numerical simulations show the influence of the FROH gain β parameter on the stability of the discretization zeros.
