Vibration mitigation devices, absorbers or dampers, passive or active, are generally the result of a rather tenuous optimization. On the one hand, these devices require a very fine tuning to be efficient, on the other hand the context of use is often defined in an approximate way. In this context, the objective of this seminar is to present the use of the info-gap method in a high-fidelity simulation context for taking into account unknowns and finding an optimal but robust result. Several illustrations of the method will be shown in the context of frequency and temperature sensitive damping devices, frequency sensitive tuned mass absorbers and active vibration control devices. An opening will be given towards a new path, that of self-adapting structures.
