Optimal Active Vibration Isolation System Design using Constrained H2 control.

Active vibration isolation systems can increase the performance over passive by mitigating trade-off in sensitivity to direct and indirect disturbances. However, potential improvement, as well optimal system design are not yet fully understood. This paper proposes an method based on constrained H2 control parametrized mechanics, where disturbance spectra of floor vibrations, actuator sensing noise explicitly taken into account. Using this method, parameters, improvement be quantified. is applied a case study show its usefulness. From study, thereby imposed constraints, it concluded that AVIS significantly improve for all considered powers.
