Trajectory-Switching Algorithm for a MEMS Gyroscope [PDF]
IEEE Transactions on Instrumentation and Measurement, 2007 The motion of a conventional force-balancing controlled gyroscope in a mode-matched operation does not have sufficient persistence of excitation, and as a result, all major fabrication imperfections cannot be identified and compensated for. This paper presents an adaptive force-balancing control for a microelectromechanical-system z-axis gyroscope ...

Thermoelastic damping in MEMS gyroscopes at high frequencies
Microsystems & Nanoengineering, 2023 AbstractMicroelectromechanical systems (MEMS) gyroscopes are widely used, e.g., in modern automotive and consumer applications, and require signal stability and accuracy in rather harsh environmental conditions. In many use cases, device reliability must be guaranteed under large external loads at high frequencies. The sensitivity of the sensor to such

System Identification of MEMS Vibratory Gyroscope Sensor [PDF]
Mathematical Problems in Engineering, 2011 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.

Gas Damping Coefficient Research for MEMS Comb Linear Vibration Gyroscope [PDF]
, 2007 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).
