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.
