Perfect observers for fractional discrete-time linear systems. (English) Zbl 1389.93044

The concept of perfect observers has been extended to fractional singular discrete-time linear systems, described by the Caputo-type (Riemann-Liouville or Grünwald-Letnikov) \(h\)-difference operators. The detectability of this class of fractional systems has been investigated.
