This paper describes a unique capacitively-sensed MEMS-based gyroscope, which utilizes rotating carrier rotate as driven force and responds to an external angular rate of yaw due to the Coriolis Effect. The basic construction and operating principles of the gyroscope are described and illustrated. MEMS-based gyroscope output is presented at different yaw angular acceleration. The raw results ob...

In this thesis report, the theory of MEMS vibratory gyroscope is introduced and discrete wavelet decomposition and reconstruction are introduced. In the first part of this work, I review the Coriolis effect and angular rate sensors, and fundamental operational principles of micro-machined vibratory gyroscopes. The MEMS gyroscopes are expected to lead to reliable, robust and high performance ang...

MEMS (Micro Electro Mechanical System) gyroscopes have been widely applied to various fields, but MEMS gyroscope random drift has nonlinear and non-stationary characteristics. It has attracted much attention to model and compensate the random drift because it can improve the precision of inertial devices. This paper has proposed to use wavelet filtering to reduce noise in the original data of M...

Silicon-MEMS gyroscope is an important part of MEMS ( Micro Electrical Mechanical System). There are some disturb ignored in traditional gyroscope that must be evaluated newly because of its smaller size (reach the level of micron). In these disturb, the air pressure largely influences the performance of the MEMS gyroscope. Different air pressure causes different gas damping coefficient for the...

In order to improve the precision of the low cost MEMS gyroscope and reduce the influence of the random drift error on the measurement system. In this paper, the Allan variance method, mean filtering method, time series analysis method and Kalman filtering technique are used to analyze and filter the random error of static output of MEMS gyroscope. The results show that the amplitude of the ran...

A signal processing technique is presented to improve the angular rate accuracy of Micro-Electro-Mechanical System (MEMS) gyroscope by combining numerous gyroscopes. Based on the conditional correlation between gyroscopes, a dynamic data fusion model is established. Firstly, the gyroscope error model is built through Generalized Autoregressive Conditional Heteroskedasticity (GARCH) process to i...
