Claim Text:
1. A mounting system for mounting machinery, and for isolating vibration therefrom, the system comprising: a support for said machinery, including a plurality of resilient mounts, and a controller for controlling the stiffness of the mounts as a function of frequency, each mount comprising a passive resilient element configured to fully support a static load of the machinery, and an active isolation element, wherein the controller is configured to control the active isolation element such that: at or below a resonant frequency of the passive resilient element, a performance parameter of the support is essentially that of the passive resilient element; and above the resonant frequency of the passive resilient element, forces generated by the passive resilient element in response to local displacements of the passive resilient element are essentially cancelled out by the active isolation element to maintain a zero stiffness of the support to excited structural resonances, and wherein said controller is configured to apply a notch filter in the transmissivity of force between the machinery and the support to attenuate transmission of a specific detected problem out-of-balance force.
