摘要

We present the experimental results of the temperature self-compensation in the RR-type force-feedback force micromechanical gyroscope (MMG). The self-compensation is based on the temperature dependence of micromechanical resonator Q-factor, which may determined by measurements of internal signals in the drive loop of MMG. For the MMG with repeatability of the temperature dependence of bias equal to 1-3°/s (in the working temperature range of -40 -+85 °C) the self-compensation gives similar to compensation from embedded into ASIC temperature sensor improvement. The described self-compensation may be more efficient for the MMG with a better repeatability or/and at the rapid temperature change.
