Systems with Fractional Variable-Order Difference Operator of Convolution Type and Its Stability

Dorota Mozyrska, Malgorzata Wyrwas

Abstract


In the paper the Grünwald–Letnikov-type linear fractional variable order discrete-time systems are studied. The conditions for stability and instability are formulated. The regions of the systems stability are determined accordingly to locus of eigenvalues of a matrix associated to the considered system.
