FFLD-Based Modeling of Fractional-Order State Space LTI MIMO Systems

This paper introduces a multivariable version of the Grunwald-Letnikov fractional-order difference (FD) and approximates it with a powerful combination of finite fractional difference (FFD) and finite Laguerre-based difference (FLD) to yield finite fractional/Laguerre-based difference (FFLD). The multivariable FFLD is effectively used to model fractional-order state-space LTI MIMO systems.
