In this work we investigate the application of some model order reduction techniques, based on Krylov subspace methods, to large linear time--invariant systems of fractional order. Theoretical and technical aspects are discussed. The effectiveness of the proposed approach is verified by numerical simulations on a test problem describing the heat conduction in electro--thermal processes involved in micro--electromechanical systems. An application in a parameter identification problem is also presented.

Abstract
In this work we investigate the application of some model order reduction techniques, based on Krylov subspace methods, to large linear time--invariant systems of fractional order. Theoretical and technical aspects are discussed. The effectiveness of the proposed approach is verified by numerical simulations on a test problem describing the heat conduction in electro--thermal processes involved in micro--electromechanical systems. An application in a parameter identification problem is also presented.File in questo prodotto:
