Szukana fraza: [Abstract = "A new class of fractional 2D linear discrete\-time systems is introduced. The fractional difference definition is applied toeach dimension of a 2D Roesser model. Solutions of these systems are derived using a 2D Z\-transform. The classicalCayley\-Hamilton theorem is extended to 2D fractional systems described by the Roesser model. Necessary and sufficientconditions for the positivity and stabilization by the state\-feedback of fractional 2D linear systems are established. Aprocedure for the computation of a gain matrix is proposed and illustrated by a numerical example."]
