This paper discusses an enhanced active vibration control concept to suppress the dynamic response associated with gear mesh frequencies. In active control application, the control of dynamic gear mesh tonal response is essentially the rejection or suppression of periodical disturbance. Our active control experimental work shows that the existence of un-controlled harmonic result in the increase at these harmonics when applying direct control to the target mesh frequencies. To address this problem, the effect of the existence of un-correlated harmonic components in error signal when applying active control to suppress the target gear mesh harmonics is examined. The proposed adaptive controller that is designed specifically for tackling gear mesh frequency vibrations is based on an enhanced filtered-x least mean square algorithm (FXLMS) with frequency estimation to synthesize the required reference signal. In this analysis, the non-Wiener solution of FXLMS algorithm will be applied to analyze the results. Furthermore, simulation studies are performed to demonstrate the characteristics caused by the non-Wiener effect of FXLMS algorithm. Based on these results, an enhancement using the adaptive linear enhancer is proposed to reduce the unintended amplification at the un-correlated harmonics.
