Adaptive feed forward active vibration control method is usually unable to achieve effective performance when the frequency of the reference signal is not consistent with the primary signal. A geometry relationship based method for cross-updating the reference signal is proposed in this paper. The initial value which contains the amplitude and phase information of the cosine and sine components is cross-updated. By orthogonalization
the amplitudes of the cosine and sine reference signals are fixed and only the phase is updated. Adopting the conventional narrowband filtered-X least mean square(FXLMS)algorithm
the other harmonic components from the residual error signal can be removed. The simulation and experiment validate that the estimated frequency of reference signal converges to the frequency of primary signal by cross-updating reference signal in the case of inaccurate frequency of the primary signal.
