Information-Based Sensor Placement for Data-Driven Estimation of Unsteady Flows
John Graff, Albert Medina, Francis Lagor
Estimation of unsteady flow fields around flight vehicles may improve flow interactions and lead to enhanced vehicle performance. Although flow-field representations can be very hi…

Experimental mitigation of large-amplitude transverse gusts via closed-loop pitch control
Girguis Sedky, Antonios Gementzopoulos, Francis D. Lagor +1
Air vehicles of all scales are susceptible to large-amplitude gusts that may lead to vehicle damage and instability. Therefore, effective physics-based control strategies and an un…

Reduced-order modeling using Dynamic Mode Decomposition and Least Angle Regression
John Graff, Xianzhang Xu, Francis D. Lagor +1
Dynamic Mode Decomposition (DMD) yields a linear, approximate model of a system's dynamics that is built from data. We seek to reduce the order of this model by identifying a reduc…
