Abstract

This paper presents an active anti-vibration control system with isolation of low-frequency vibration. A proper dynamic model of the anti-vibration control system is derived for controller design in that the identification scheme for a mathematic model is proposed. The model reference controls of the anti-vibration system with the sky-hook damper control and impedance control are analyzed respectively. An illustrated example of a single-degree-of-freedom anti-vibration system driven by a linear servomotor is given to verify the performance of the proposed control design. Experimental results are presented to validate that the peak resonance value of 0dB within a frequency of 10Hz can be achieved successively.
