Filtered-X LMS vs repetitive control for active structural acoustic control of periodic disturbances KU Leuven
This paper presents a comparison of repetitive control and narrowband filtered-X LMS feedforward control, both applicable in the field of active structural acoustic control (ASAC) and active noise control (ANC) of periodic disturbances. This can be useful for example in rotating machinery, where the disturbance is often determined by the rotational speed. A frequency domain relation between the disturbance and the error signal is presented for ...
