Rate gyro measuring method, involves adding multiplied value of model of rate gyro scale factor value and output rate gyro signal with model of rate gyro skew value to estimate mechanical rotation applied around axis of resonator

摘要

The method involves establishing a gain control of a vibration amplitude control loop (3). A correspondence between the rate gyro scale factor and skew values and the gain control signal values is established and stored. A multiplied value of a model of the scale factor value and an output rate gyro signal is added with a model of the skew value to estimate a mechanical rotation applied around a sensitive axis of a resonator (1). The gain control of the vibration amplitude control loop is established such that the control varies as a monotonic function of an internal temperature of the resonator in a given temperature range. An independent claim is also included for a rate gyro measuring device.
