Non-axisymmetric Coriolis Vibratory Gyroscope with Whole Angle, Force Rebalance,
This paper presents detailed performance status and projections for the silicon MEMS Quadruple Mass Gyroscope (QMG) – a unique high Q, lumped mass, mode-symmetric Class II Coriolis Vibratory Gyroscope (CVG) with interchangeable whole angle, self-calibration, and force rebalance mechanizations. Analysis of a QMG sealed without getter with a Q-factor of 1e3 reveals an Angle Random Walk (ARW) of 0...
متن کاملTwo Novel Measurements for the Drive-Mode Resonant Frequency of a Micromachined Vibratory Gyroscope
To investigate the drive-mode resonance frequency of a micromachined vibratory gyroscope (MVG), one needs to measure it accurately and efficiently. The conventional approach to measure the resonant frequency is by performing a sweep frequency test and spectrum analysis. The method is time-consuming and inconvenient because of the requirements of many test points, a lot of data storage and off-l...
متن کاملSystem Identification of MEMS Vibratory Gyroscope Sensor
Fabrication defects and perturbations affect the behavior of a vibratory MEMS gyroscope sensor, which makes it difficult to measure the rotation angular rate. This paper presents a novel adaptive approach that can identify, in an online fashion, angular rate and other system parameters. The proposed approach develops an online identifier scheme, by rewriting the dynamic model of MEMS gyroscope ...
متن کاملDynamics of Micromechanical Coriolis Vibratory Gyroscopes
A general approach to the analysis of the dynamics of different types of micromechanical vibratory gyroscopes is considered in this paper. Specifically, we investigate and analyse the dynamics of singlemass gyroscopes for both fixed and rotating base. Generalized motion equations are derived and solved by means of method of averaging. Amplitude and phase responses of the sensitive element along...
متن کاملControl of MEMS Coriolis Vibratory Gyroscopes
This application note gives an overview of different control mechanisms for MEMS Coriolis Vibratory Gyroscopes (CVG) and how they are implemented using the commercial off-the-shelf HF2LI Lock-in Amplifier. A MEMS gyroscope is a micro-machined inertial device that can measure the angle of orientation or the angular rate of rotation. The principle relies on a vibrating structure that is suspended...
