Section: New Results

Some remarks on the Walton and Marshall method for neutral delay systems

Participants : Catherine Bonnet, Islam Boussaada, Le Ha Vy Nguyen, Marianne Souaiby.

The Walton and Marshall method allows to determine stability windows of delay systems of the retarded and neutral type. We noticed that some delay systems of the neutral type do not behave as claimed in [66] and analyzed carefully the position of the poles of such systems in the right half-plane.
