Control of magnetorheological mount

A system for controlling a hydraulic mount between an object and a base, the object having a bounce resonance frequency, the system comprising:

• means for modifying at least one tunable parameter of a control system of the mount based on the bounce resonance frequency of the object;
• means for generating a first acceleration signal indicative of an acceleration of said object;
• means for generating a second acceleration signal indicative of an acceleration of said base;
• means for determining a relative acceleration across the mount based on the first and second acceleration signals;
• means for generating a control signal responsive to the relative acceleration based on the at least one tunable parameter;
• and
• means for controlling the flow of MR fluid in the mount responsive to the control signal to minimize the relative acceleration across the mount over a predetermined band of frequencies.

A control system for a hydraulic mount positioned between a vibrating object and a base, said vibrating object having a bounce resonance frequency, the system comprising:

• means for generating a first acceleration signal indicative of an acceleration of said object;
• means for generating a second acceleration signal indicative of an acceleration of said base;
• means for determining a relative acceleration across the mount based on the first and second acceleration signals;
• means for generating a control signal corresponding to the relative acceleration;
• means for controlling the flow of MR fluid in the mount responsive to the control signal;
• means for tuning the control system to minimize the relative acceleration across the mount at and around the bounce resonance frequency of the object.
