Fractional-order model analysed in this study, including a constant phase inertance (CPL) and a constant phase compliance (CPC) composed by a frequency-dependent fractional inertia (FrL) and a frequency-dependent fractional compliance (FrC) associated with their respective fractional exponents α and β. The ability of the fractional terms to describe the resistive and reactive respiratory properties, depending of α and β values is also described
