Stability analysis of fractional neutral systems with commensurate delays
Participants : Le Ha Vy Nguyen, Catherine Bonnet.
Fractional neutral systems with commensurate delays have chains of poles aymptotic to vertical lines. The case where the imaginary axis is an asymptotic one is interesting. Indeed, if the system has some chains of poles asymptotic to the imaginary axis, then the fact that all poles lie in the open left half-plane does not guarantee the
This kind of systems was studied in [97] , [104] . In [97] , systems with single
chains of poles asymptotic to the imaginary axis was considered and
necessary and sufficient conditions for
