ABSTRACT:
The present invention relates to an active mount system in which a vibration sensor such as a force gauge or an accelerometer senses vibrational forces transmitted through a resilient mount by a load such as a machine. The invention further includes a digital narrow-band least mean square filter that receives a sinusoid synchronous with the rotating machinery and an error signal from the load cell and generates a corrective signal to be amplified and transmitted to the electromagnet which supplies an attenuating force to the resilient mount in response to the signal. As an alternative, a wide frequency range control can be realized by the use of a wide frequency range, high gain amplifier and multi-filter phase compensation circuitry to generate the corrective force signal which is amplified and transmitted to the electromagnet.
