Design of a Novel MEMS Gyroscope Array
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 کاملPull-In Instability and Vibrations of a Beam Micro-Gyroscope
Gyroscopes are used as rotation rate sensors. Conventional gyroscopes are heavy and bulky, which creates important problems regarding their usage in different applications. Micro-gyroscopes have solved these problems due to their small size. The beam micro-gyroscope is one of the popular types of inertial sensors. Their small dimensions and low energy consumption are key reasons for their popul...
متن کاملA Novel Non-driven Structural MEMS-based Gyroscope
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...

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 ...
