Abstract

This article deals with the reduction of structural vibrations. Two approaches are possible to tackle this problem, either a passive method with dampers, or an active method with actuators that are controlled in order to decrease or even cancel the vibrations in the structure. The second method is used here. The objective is to control the damping of uncertain plants. The proposed methodology is based on iso-damping contours and CRONE control. The iso-damping contours are defined thanks to fractional order integration in the Nichols plane and are graduated by the value of the damping factor of the closed-loop response. The CRONE control is a robust control method that also uses fractional order integration. The methodology is here applied to a multivariable plant that is an aircraft wing model made with a beam and a tank whose different levels of fillings are considered as uncertainties.
