Abstract:
A system of active vibration control, comprising:a cryogenic cooling system characterized by a vibration transfer function, which requires vibration transfer function coefficients; anda vibration controller coupled to the cooling system, comprising means for generating vibration transfer coefficients in response to a triggering event, wherein said means for generating vibration transfer coefficients automatically obtains a first set of vibration transfer coefficients when said cryogenic cooling system is turned on, wherein said means for generating vibration transfer coefficients automatically obtains a second set of vibration transfer coefficients when said cryogenic cooling system reaches its operating temperature and wherein said means for generating vibration transfer coefficients obtains at least one additional set of vibration transfer coefficients at any time in response to a recalibration signal.
