Claim Text:
1. A method for suppression of vibration that occurs in a control system, the method to be implemented by the control system and comprising the steps of: (A) receiving a to-be-detected signal obtained within a time period under the influence of vibration; (B) adjusting a center frequency of a band-pass filter, and subjecting the to-be-detected signal to processing by the band-pass filter to result in a bandpass-filtered signal; (C) performing signal processing upon the bandpass-filtered signal to obtain a converted result corresponding to a current center frequency of the band-pass filter; (D) determining whether a scanning process is completed, and when the scanning process is determined to be not completed, repeating steps (B) and (C) to result in plural entries of the converted results; (E) when the scanning process is determined to be completed in step (D), determining a maximum value among the plural entries of the converted results, and determining the corresponding center frequency to serve as an interference frequency associated with the vibration that occurs in the control system; and (F) setting the interference frequency as an operating frequency of a notch filter of the control system so as to suppress the vibration.
