Multiple floods interactions shape riparian plant communities and diversity [PDF]
Scientific ReportsDisturbances are pivotal ecological events that influence the formation of biological communities. Although disturbances have been studied in isolation, studies recently have highlighted the interaction among multiple disturbances.

ROBUST REJECTION OF PERIODIC AND ALMOST PERIODIC DISTURBANCES [PDF]
IFAC Proceedings Volumes, 2005 Abstract We present algorithms to exponentially reject periodic and almost periodic disturbances, the motivating application being a rejection of reel eccentricity induced disturbances in tape-drive systems. The prevalent periodic disturbance rejection algorithms rely on a constant gain approximation of the system at a particular frequency. These are

Journal of Low Frequency Noise, Vibration and Active Control, 2021 Vibrations are usually caused by continuous disturbances with large amplitudes. Different from other control methods, disturbance rejection control is a potential method, which considers the unknown disturbances in the control design.

Observer based tuning techniques and integrated SAW torque transducers for two-inertia servo-drive systems [PDF]
, 2005 A controller design and tuning methodology is proposed that facilitates the rejection of periodic load-side disturbances applied to a torsional mechanical system, whilst simultaneously compensating for the disturbance observer's inherent phase delay ...
