Sampling decomposition and asymptotic zeros behaviour of sampled-data SISO systems. An eigenvalue-based approach Article uri icon


  • This paper deals with some problems concerning the zero behaviour of a class of sampled-data SISO systems. More precisely, given a continuous-time system, we derive all the sampling intervals guaranteeing the invariance of the number of unstable zeros in each interval. To perform such an analysis, we adopt an eigenvalue perturbation-based approach. Various illustrative numerical examples complete the presentation. © The authors 2015.
