System 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 کاملDesign and Analysis of a MEMS Comb Vibratory Gyroscope
MEMS (Micro-electro-mechanical Systems) refer to devices or systems integrated with electrical and mechanical components in the scale of microns. Due to its small size, low cost, low power consumption and high efficiency, MEMS technology has been widely used in many fields. In this paper, a novel comb-driven, differential capacitance sensing MEMS vibratory gyroscope based on glass-silicon-glass...
متن کاملDesign 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 Modeling of a MEMS Vibratory Gyroscope and Integration to Circuit Simulation
Recently, consumer applications have dramatically created the demand for low-cost and compact gyroscopes. Therefore, on the basis of microelectromechanical systems (MEMS) technology, many gyroscopes have been developed and successfully commercialized. A MEMS gyroscope consists of a MEMS device and an electrical circuit for self-oscillation and angular-rate detection. Since the MEMS device and c...
