A demonstration of active vibration isolation using decentralized velocity feedback control
A demonstration of active vibration isolation using decentralized velocity feedback control
This paper describes a demonstrator designed to show the way in which a four-channel active vibration system can be implemented using an analogue decentralized controller. Each mount consists of a resilient element in parallel with an electrodynamic actuator, and an accelerometer attached to the flexible equipment. A measure of the control performance is the sum of the squared velocities of the equipment at the mount positions. The controller is shown to achieve about 20 dB reduction in the equipment vibration at the fundamental resonance frequencies of the mounted equipment.

Abstract
This paper describes a demonstrator designed to show the way in which a four-channel active vibration system can be implemented using an analogue decentralized controller. Each mount consists of a resilient element in parallel with an electrodynamic actuator, and an accelerometer attached to the flexible equipment. A measure of the control performance is the sum of the squared velocities of the equipment at the mount positions. The controller is shown to achieve about 20 dB reduction in the equipment vibration at the fundamental resonance frequencies of the mounted equipment.
