Abstract

Abstract: We studied an active vibration isolator's performance for vibration suppression in this article. A modified FxLMS control method is presented by replacing the weights update law of FxLMS with NR-LMS algorithm and its reference signals is got from the sensors' output. Control simulation is performed by employing the models identified and the modified FxLMS method, the results indicate that the modified FxLMS method can suppress the vibration effectively and the control performance can be improved by minimizing the divergence between the secondary plant model and the practical second plant.
