In this note, we address some problems concerning the zero behavior of some class of Sampled-Data SISO systems. More precisely, given a continuous-time system, we obtain the sampling intervals guaranteeing the invariance of the number of unstable zeros in each interval. To performsuch an analysis, we adopt an eigenvalue perturbation-based approach. Various illustrative numerical examples complete the presentation. cIFAC Copyright 2010. © 2010 IFAC.
