【発明の名称】適応制御装置
Document Type and Number:
Japanese Patent JP2756629
Kind Code:
B2
Abstract:
An adaptive control device is arranged to cancel periodic noises without any malfunction and delay if aperiodic noises are mingled in the periodic noises. In the adaptive control device, the reference signal sensor senses a reference signal. The reference signal is filtered in the adaptive filter. The filtered signal is applied to the actuator serving as an electrical-mechanical converting unit so that the signal may be added to the input noises. The added result corresponding to an error is converted into an electric signal through the effect of the sensor. The electric signal is applied to the periodic signal separator for separating the signal into a periodic error and an aperiodic error. The coefficient updating unit operates to update a tap coefficient of the adaptive filter by employing an algorithm such as an LMS by using the separated periodic error and the signal filtered by the transfer characteristic compensating filter.
