Abstract
A vibration control system includes a mechanical system which generates vibration; a sensor configured to measure the vibration and generate a vibration signal thereof, and a processor configured: (a) receive a vibration signal from a sensor in a mechanical system; (b) model the vibration signal using a time-domain function; (c) adjust one of an amplitude coefficient and a phase coefficient of the modeled vibration signal; (d) output a control signal corresponding to the modeled vibration signal to the mechanical system so as to reduce the vibration; and (e) receive another vibration signal from the sensor. Steps (c)-(e) are repeated when the average value of the vibration signal is greater than a predetermined value. A method for vibration control is also disclosed.
