The stability of -dimensional linear fractional differential systems
with commensurate order and the corresponding
perturbed systems is investigated. By using the Laplace transform,
the asymptotic expansion of the Mittag-Leffler function, and
the Gronwall inequality, some conditions on stability and asymptotic
stability are given.
