Frequency Domain Identification of a 1-DoF and 3-DoF Fractional-Order Duffing System Using Grünwald–Letnikov Characterization

Fractional-order models provide a powerful framework for capturing memory-dependent and viscoelastic dynamics in mechanical systems, which are often inadequately represented by classical integer-order characterizations. This study addresses the identification of dynamic parameters in both single-deg...
