Title:
ACTIVE VIBRATION AND NOISE CONTROL DEVICE AND ACTIVE VIBRATION AND NOISE CONTROL CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2017/135012
Kind Code:
A1
Abstract:
An active vibration and noise control device robust against outside disturbances, and an active vibration and noise control circuit are provided. An adaptive control circuit (50) of this active vibration and noise control device (24) has autocorrelation value calculation units (80a, 80b) which calculate an autocorrelation value (Va1, Va2) of an error signal (e1) or of a target signal (Star), which is a reference signal (Sr1) or a standard signal (Pcrk), and a canceling output limiting unit (84) which determines whether or not an autocorrelation value (Va1, Va2) is less than an autocorrelation threshold value (THva), and limits increases in the cancelling output (CS) if it is determined that the autocorrelation value (Va1, Va2) is less than the autocorrelation threshold value (THva).
