چکیده
Abstract The noise signal in the gyroscope is divided into four levels: sampling frequency level, device bandwidth resonant and carrier level. In this paper, dual-mass MEMS analyzed. Based on variational mode decomposition (VMD) algorithm, a novel reduction method proposed. VMD with different four-level center frequencies used to process original output of gyroscope, results are analyzed by Allan analysis variance, which shows that ARW increased from 1.998*10 ?1 °/?h 1.552*10 ?4 °/?h, BS 2.5261°/h 0.0093°/h.

Research on Ship-Radiated Noise Denoising Using Secondary Variational Mode Decomposition and Correlation Coefficient
As the sound signal of ships obtained by sensors contains other many significant characteristics of ships and called ship-radiated noise (SN), research into a denoising algorithm and its application has obtained great significance. Using the advantage of variational mode decomposition (VMD) combined with the correlation coefficient for denoising, a hybrid secondary denoising algorithm is propos...
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...

This paper reports a novel four degree-of-freedom (DOF) MEMS vibratory gyroscope. A MEMS gyroscope array is then presented using the novel gyroscope unit. In the design of the proposed 4-DOF MEMS vibratory gyroscope, the elements of the drive-mode are set inside the whole gyroscope architecture, and the elements of sense-mode are set around the drive-mode, which thus makes it possible to combin...
متن کاملDenoising via Empirical Mode Decomposition
In this paper a signal denoising scheme based a multiresolution approach referred to as Empirical mode decomposition (EMD) [1] is presented. The denoising method is a fully data driven approach. Noisy signal is decomposed adaptively into intrinsic oscillatory components called Intrinsic mode functions (IMFs) using a decomposition algorithm algorithm called sifting process. The basic principle o...
