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.

Modal Parameter Identification of Recursive Stochastic Subspace Method
Symmetry, 2023 In bridge health monitoring, in order to closely monitor the structural state changes of the bridge under heavy traffic load and other harsh environments, the monitoring system is required to give the change process of structural modal parameters. Due to the symmetric variables of bridge monitoring during operation, the evaluation needs to be completed
