Industrial noise often has a periodic or quasiperiodic component embedded within the broadband noise. An active noise control system is presented to cancel these harmonics. A combination of generalized phase-locked loop (PLL) and a Filtered-X Least Mean Square (FXLMS) method is used. Large changes in the fundamental frequency can be tracked. Simulations results are presented to demonstrate the effectiveness of the proposed technique.
