Robust vibration control of ﬂexible panel:modeling and simulation

Purpose – This paper aims to develop a robust controller to control vibration of a thin plate attached with two piezoelectric patches in the presence of uncertainties in the mass of the plate. The main goal of this study is to tackle dynamic perturbation that could lead to modelling error in ﬂexibl...
