The adaptive vibration control of systems excited by forces of periodically varying frequencieswas dis-
cussed. The presented adaptive controlwas realized on the basis of tracking of time-varying frequencies and amethod for
online frequency estimation, filtering and controlwas proposed. Based on the principle of subspace identification, the
time-varying frequencieswere estimated from the recursively computed autocorrelation ofmeasured signals.
