Abstract

Journal of Vibration and Control, Ahead of Print.
The feedback filter-x least mean squares (FxLMS) algorithm effectively addresses challenges posed by difficult-to-obtain reference signals and secondary path variations through online modeling of the secondary path. However, control stability may be ...
