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 ...

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.

A closed-loop digitally controlled MEMS gyroscope with unconstrained Sigma-Delta force-feedback [PDF]
, 2009 In this paper, we describe the system architecture and prototype measurements of a MEMS gyroscope system with a resolution of 0.025 degrees/s/root Hz. The architecture makes extensive use of control loops, which are mostly in the digital domain.
