Active vibration control system

The Journal of the Acoustical Society of America, 1995
An adaptive control circuit is responsive to a reference signal, i.e. an output from a sensor which senses vibration from a vibration source, for generating a cancelling signal having a transfer characteristic inverse to a transfer characteristic of vibration from the vibration source to a human body.

A semi-active shunted piezoelectric tuned mass damper for robust vibration control

Journal of Vibration and Control, 2021
Tuned mass dampers are well-known devices for efficient reduction of structural vibrations; however, they can only control the vibration of a single mode in a narrow frequency range and are not easily retunable.

Active Control Of Flow-induced Vibration

Journal of Sound and Vibration, 1993
Abstract The active control of flow-induced oscillations, specifically, vortex-induced oscillations of circular cylinders and galloping oscillations of circular cylinders and galloping oscillations of a square prism, are considered. In the case of vortex-induced oscillations, the vibrating cylinder is modeled as a single-degree-of-freedom (sdof ...

Off-axis modal active vibration control of rotational vibrations

2012 IEEE/ASME International Conference on Advanced Intelligent Mechatronics (AIM), 2012
Collocated active vibration control is an effective and robustly stable way of adding damping to the performance limiting vibrations of a plant. Besides the physical parameters of the Active Damping Unit (ADU) containing the collocated actuator and sensor, its location with respect to the compliances in the plant plays an important role in the ...

Active Vibration Control for Aeroengines

2021
The problem of aero-engine vibration has always been the focus and difficulty of many scholars at home and abroad. Vibration control is an important research direction in the field of aeroengine vibration engineering. In order to solve the problems of poor adaptability to passive vibration isolation and insufficient control effect of aero-engines, this
