The pointwise completeness and the pointwise degeneracy of linear discrete-time different fractional order systems [PDF]

open access: yesBulletin of the Polish Academy of Sciences: Technical Sciences, 2020
Necessary and sufficient conditions for the pointwise completeness and the pointwise degeneracy of linear discrete-time different fractional order systems are established. It is shown that if the fractional system is pointwise complete in one step (q = 1)
