ACTIVE VIBRATION DAMPING METHOD Russian patent published in 2023 - IPC G10K11/178 

FIELD: vibroacoustics.

SUBSTANCE: invention relates to methods for actively suppressing vibration effects. A method for active vibration damping includes: placing residual vibration sensors in places requiring vibration damping, transmitting a signal from reference sensors and signals from residual vibration sensors to the unit for calculating the parameters of a compensating action device, determining the parameters of the compensating signal shaping filters, generating compensating signals when the help of the conversion by the forming filters of the signal from the reference sensors. At the same time, the parameters of the shaping filters of the compensating signal are determined by a time-limited sample of signals from the reference sensors and residual vibration sensors, which does not require calculation and constant correction of the parameters of the shaping filters in real time, and the least squares method is used as a computational method.

EFFECT: reduction in the tuning time of the algorithm for determining the parameters of the compensating signal while simultaneously reducing the requirements for computing power of the signal processing device used by eliminating high-performance real-time computing.
