Uncertainty-Based Fusion Method for Structural Modal Parameter Identification [PDF]
SensorsThe structural modal parameter identification method can be classified into time-domain and frequency-domain methods. Practically, two types of methods are characterized by different advantages, and the estimated modal parameters are always subjected to ...

Uncertainties on modal parameters by operational modal analysis [PDF]
Mechanics & Industry, 2014 Lorsqu’on fait une analyse modale opérationnelle sur des structures en fonctionnement, sans connaître les forces de perturbation, ni le nombre de fréquences importantes qui excitent le système mécanique, on doit se poser la question sur la validité de l’estimation des paramètres modaux (notamment le taux d’amortissement) et sur la précision des ...

Modal control based on direct modal parameters estimation [PDF]
Journal of Vibration and Control, 2017 Modal active control is based on a state model that requires the identification of modal parameters. This identification can typically be done through a rational fraction polynomial algorithm applied in the frequency domain. This method generates numerical problems when estimating high-order models, particularly when moving from the basis of orthogonal

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.

Discrete and Modal Early Warning of Coal and Gas Outburst Based on Time Series of Gas Emission
Meikuang Anquan, 2020 In order to realize the dynamic and real-time early warning of coal and gas outburst danger in working face, a discrete modal early warning method based on time series of gas emission is proposed. The methane monitoring data of the coal mine in the real
