Title:
駆動制御装置、および駆動制御方法、並びにプログラム
Document Type and Number:
Japanese Patent JP7459882
Kind Code:
B2
Abstract:
The present disclosure relates to a drive control device, a drive control method, and a program that allow for an improvement in detection accuracy of a multi-IMU.Angular velocities supplied from a plurality of inertial measurement units (IMUs) are acquired, drive frequencies of the plurality of IMUs are calculated on the basis of acquisition timings of the acquired angular velocities, and on the basis of the drive frequencies of the plurality of IMUs, in a case where an interval between peak frequencies of the drive frequencies is smaller than 1/2 of a half width of a drive frequency distribution, control is performed so as to change the drive frequencies by heating or cooling temperatures of the IMUs so that the interval can be widened. The present disclosure can be applied to a multi-IMU.
