Multivariable data-driven uncertainty modeling for robust active vibration isolation

Robustness is of vital importance for any feedback controlled system. An important example of such a feedback controlled system is an active vibration isolation system (AVIS), which is used to isolate highly accurate systems from external disturbances in multiple degrees-of-freedom. The underlying idea of vibration isolation is based on the concept of skyhook damping, see [1]. Model-based robust control designs based on H∞-optimization/μ-synthesis provides a structured approach for controller design for uncertain systems.
