Fractional robust control with iso-damping property

Abstract

This article deals with the problem of the reduction of structural vibrations with isodamping property. The proposed methodology is based on: - a contour defined in the Nichols plane and significant of the damping ratio of the closed-loop response - a robust control method that uses fractional order integration. The methodology is applied to an aircraft wing model made with a beam and a tank whose different levels of fillings are considered as uncertainties.
