Abstract

Active vibration isolation systems can increase the performance over passive vibration isolation systems by mitigating the trade-off in sensitivity to direct and indirect disturbances. However, the potential performance improvement, as well as the optimal system design are not yet fully understood. This paper proposes an optimal system design method based on constrained H2control and parametrized mechanics, where the disturbance spectra of the floor vibrations, actuator and sensing noise are explicitly taken into account. Using this method, the optimal system parameters, as well as the potential performance improvement can be quantified. This method is applied to a case study to show its usefulness. From this case study, and the thereby imposed constraints, it can be concluded that AVIS can significantly improve the performance for all considered direct disturbance powers.
