Systems and Methods for Determining Rotation from Nonlinear Periodic Signals |
摘要 |
Systems and methods are disclosed herein for determining rotation. A gyroscope includes a drive frame and a base, the drive frame springedly coupled to the base. The gyroscope includes a drive structure configured for causing a drive frame to oscillate along a first axis. The gyroscope includes a sense mass springedly coupled to the drive frame. The gyroscope includes a sense mass sense structure configured for measuring a displacement of the sense mass along a second axis orthogonal to the first axis. The gyroscope includes measurement circuitry configured for determining a velocity of the drive frame, extracting a Coriolis component from the measured displacement, and determining, based on the determined velocity and extracted Coriolis component, a rotation rate of the gyroscope. |

1. A gyroscope for determining a rotation rate, the gyroscope comprising:
a drive frame springedly coupled to a base of the gyroscope; a drive structure configured for causing a drive frame to oscillate with respect to a first axis; a sense mass springedly coupled to the drive frame; a sense mass sense structure configured for measuring a displacement of the sense mass along a second axis orthogonal to the first axis; and measurement circuitry configured for:
determining a velocity of the drive frame,extracting a Coriolis component from the measured displacement, anddetermining, based on the determined velocity and extracted Coriolis component, the rotation rate. |
