Title:
METHOD AND DEVICE FOR CONTROLLING TRANSMITTING FORCE OR SIGNAL OF VIBRATION OR THE LIKE
Document Type and Number:
Japanese Patent JP2008287635
Kind Code:
A
Abstract:

To reduce vibration or noise generated in a base body, resulting from vibration of a vibration source as much as possible.

A vibration of the base body is detected as an error signal e, a build-up point of a certain trigger level is read from a frequency contained in the vibration by use of an error signal before one cycle sampling or before two or more cycle samplings to generate a reference signal x of a constant-amplitude sine wave having the same phase as that of the vibration of the base body with the time interval as a cycle. A filter coefficient W of an adaptation algorithm is updated using the reference signal x to minimize the error signal e, and a control output Y is generated and updated by convolution integration of the filter coefficient W and the reference signal x.
