Design on the Driving Mode of MEMS Vibratory Gyroscope
Driving mode of MEMS (Micro-Electro-Mechanical Systems) Vibratory Gyroscope is discussed in the paper. We analyze the closed-loop circuit of MEMS gyroscope from two aspects of amplitude fixed and frequency locking. In the amplitude fixed circuit, Automatic Gain Control (AGC) circuit is employed to update the amplitude of the driving force, together with a PI controller to improve the accuracy a...
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 کاملModel Predictive Control of MEMS Vibratory Gyroscope
This paper presents a MPC (Model Predictive Control) algorithm for MEMS vibratory gyroscopes based on force-balancing control strategy. In the proposed MPC method, using a set of orthonormal basis functions named Laguerre functions, a new prediction and optimization technique is designed. To enhance the capability of proposed MPC method for tracking time-varying reference trajectories, first a ...
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 کاملA Mode Matched Triaxial Vibratory Wheel Gyroscope with Fully Decoupled Structure
To avoid the oscillation of four unequal masses seen in previous triaxial linear gyroscopes, a modified silicon triaxial gyroscope with a rotary wheel is presented in this paper. To maintain a large sensitivity and suppress the coupling of different modes, this novel gyroscope structure is designed be perfectly symmetrical with a relatively large size of about 9.8 mm × 9.8 mm. It is available f...
