Discrete-time polynomial control systems described by the Grünwald-Letnikov h-type difference operator are considered. For this class of systems the observability problem is studied. Since the crucial idea of systems’ observability is related to choosing inputs based only on output measurements, different aspects to this problem are discussed.
