MEMS VIBRATORY GYROSCOPE THESIS

Micromachined vibratory gyroscopes with imperfections. A novel temperature compensation method for a MEMS gyroscope oriented on a periphery circuit. Digital self-oscillation driving technology for silicon micro machined gyroscopes. In this work, the gyroscope works in sense-mode open-loop mode, at this time, the mechanical sensitivity and the bandwidth are contradictory, and the bandwidth is 0. This paper proposes an effective method to calibrate the microelectromechanical systems MEMS vibratory gyroscope based on the virtual Coriolis force. The values are shown in Table 1. In [ 16 ], a calibration method based on the virtual Coriolis force was used to measure the frequency response of the MEMS structure, but this theory and the experiment results did not reflect the detailed nonlinear characteristic of the scale factor.

The value of non-linearity is ppm.

This method calibrates the gyroscope without the turntable and makes the calibration process more convenient. Introduction Microelectromechanical systems MEMS vibratory gyroscopes have had important applicable value in various fields, such as national economy, national defense, military, and navigation fields, for the past few years [ 1 ].

The vibdatory PCB is the sense loop with the virtual Coriolis force calibration circuit. Then, the output signal of gygoscope gyroscope under the virtual Coriolis force calibration condition is as follows:.

K p r e is the pre-amplifier, and V s t o t a l is the output of the sense mode. Some literature has presented several calibration methods without using turntables and angular vibrational tables.

In [ 16 ], a calibration method based on the virtual Coriolis force was used to measure the frequency gyroecope of the MEMS structure, but this theory and the experiment results did not reflect the detailed nonlinear characteristic of the scale factor. The first PCB connects the structure chip, is the interface, and processes the weak signals.

Principle Analysis of MEMS Gyroscopes The working principle of the MEMS vibratory gyroscope can be equivalent to a second-order mass-damping-spring system; its drive and sense shafts are x – and y -axis, and the angular rate is input along its sensitive shaft, the z-axis.

The linear fit equation is shown as below. The resonant frequencies of the drive and sense mode are Optimization and experimentation of dual-mass MEMS gyroscope quadrature error correction methods. Therefore, if the vibrational amplitude of the oscillator is stable, the input angular rate will be directly proportional to the Coriolis tesis. The values are shown in Table 1.

So, some more convenient and more accurate method than the traditional method is needed to obtain the mechanical characteristic of the MEMS gyroscopes. A MEMS vibratory gyroscope with more extensive applications must have both a better static characteristic and a better dynamic characteristic, and the scale factor is an important index to determine the two characteristics [ 2 ].
