This article considers the linear autonomous systems involving Hilfer fractional derivative. Starting from the generalized version of the well-known Matignon’s stability result for Caputo systems, we present a detailed portrayal of the stability of linear fractional-order systems with the Hilfer derivative. We sketch the phase portraits of such systems in the two-dimensional case. The relation between the singular points and the zeros of Mittag–Leffler functions is also presented.
