A New Robust Four Degree-of-Freedom Gyroscope Design

Abstract:

Article Preview

This paper presents a new design of vibratory four degree-of-freedom (DOF) gyroscope, which is inherently robust to keep stable sensitivity under changes of environmental temperature and pressure. The frequency response of the gyroscope has two resonant peaks close to each other, and the operating range is in the flat region between the two peaks. Simulation results show that the sensing amplitude increases by only 1.6% when the temperature rises from 25°C to 75 °C, and drops by only 6% when the pressure increases from 0.1 to 1 Torr.
