Design of a Novel MEMS Gyroscope Array [PDF]
Sensors, 2013 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 ...

Modal parameter identification of a MEMS gyroscope [PDF]
Proceedings of the 2000 American Control Conference. ACC (IEEE Cat. No.00CH36334), 2000 This paper reports the experimental system identification of the Jet Propulsion Laboratory microelectromechanical (MEMS) vibrational rate gyroscope. A high-order two-input/two-output transfer function for the microgyroscope is identified and mapped to a three-mode rigid plate model that reveals the orientation of important vibrational modes.
